Who Really Runs Your Life? Living Under the Authority of Jesus
Who runs your life?
Your work? Your children? Your parents? Your bank account? Or perhaps you would simply say, "Myself."
We often think of ourselves as being in control of our lives. We make plans, pursue careers, raise families, manage finances, and decide what we want our future to look like. Even as Christians, it is easy to fit Jesus into the life we have already built, rather than allow Him to define what our lives are meant to be.
But the opening chapter of Mark's Gospel presents a very different picture.
As Jesus begins His public ministry, He steps directly into the ordinary lives of people. He meets fishermen at their workplace, teaches in a synagogue, and enters a friend's home where a woman is suffering from a fever.
These are three ordinary settings: work, worship, and home.
Yet in each place, something extraordinary becomes clear: Jesus has authority over everything.
Mark wants us to understand that Jesus is not simply another religious teacher or a remarkable man with unusual abilities. He is the Son of God, the One whose authority extends over every part of human existence.
In Mark 1:16–34, we see three dimensions of His authority.
1. The Authority to Call: Our Lives Are for His Service
Jesus approaches four fishermen: Simon, Andrew, James, and John.
They are not wandering around looking for a new purpose. They are working. Fishing is their livelihood, and they are part of established family businesses. They have careers, responsibilities, and presumably plans for the future.
Then Jesus says two simple words:
"Follow me."
He does not invite them to consider an interesting opportunity. He does not ask them to think about it and get back to Him later. He calls, and they follow.
This is the authority of Jesus.
But notice that His calling comes with a purpose:
"Follow me, and I will make you become fishers of men." (Mark 1:17)
They are being called from fishing for fish to gathering people into God's kingdom. Their lives are no longer centred on their own occupations and ambitions. They have been given a new mission.
This is an important distinction about what it means to follow Jesus.
Today, we use the word follow very casually. We follow people on Instagram, X, YouTube, and other social media platforms. Following someone usually means keeping up with what they are doing while continuing to live our own lives.
Following Jesus is entirely different.
It is not simply having a window into His world. It is allowing Him to enter our world and redirect the purpose of our lives.
Not everyone is called to leave their occupation, family, or home as the first disciples did. But every Christian is called to a life of service in God's kingdom.
We see this later in the same passage when Jesus heals Simon Peter's mother-in-law. After Jesus takes her by the hand and raises her up, Mark tells us:
"And the fever left her, and she began to serve them." (Mark 1:31)
At first glance, this might sound like an uncomfortable detail. She has just recovered from a fever, and immediately she is serving others.
But the word translated as "serve" carries a much deeper meaning in Mark's Gospel. It is used to describe the ministry of angels, the service of Jesus Himself, and the ministry of the women who followed Him.
Jesus says in Mark 10:45:
"For even the Son of Man came not to be served but to serve, and to give his life as a ransom for many."
The point is not that this woman was expected to return to household chores immediately after being sick. Rather, it is that Jesus restores people so that they may participate in His kingdom and serve others.
When Jesus restores us, He restores us for service.
This challenges our understanding of Christian life. We sometimes think of faith as something that improves our personal lives, gives us comfort, and helps us achieve our goals.
But following Jesus means something more. Our time, work, resources, homes, and abilities are no longer simply our own. They become opportunities to serve Christ and His people.
The early church understood this. Believers shared what they had, opened their homes to others, and cared for those in need. Their lives were no longer centred on themselves.
The question is not merely whether Jesus has a place in our lives. The question is whether our lives have been placed at His disposal.
2. The Authority to Teach: His Word Is the Final Word
After calling His disciples, Jesus enters the synagogue in Capernaum and begins to teach.
The people are astonished because He teaches differently from the scribes.
The scribes often explained Scripture by referring to the interpretations of other teachers and rabbis. Their authority was largely built upon previous interpretations and respected traditions.
Jesus, however, teaches with an authority they have never encountered.
Mark writes:
"And they were astonished at his teaching, for he taught them as one who had authority, and not as the scribes." (Mark 1:22)
Jesus does not need to appeal to another teacher to establish the meaning of God's Word. He speaks with His own divine authority.
There is an important difference here.
Human knowledge develops. Scientific textbooks are revised. New discoveries challenge previous assumptions. What we consider established knowledge today may be reconsidered tomorrow.
Even our understanding of many social and philosophical questions changes over time.
But Jesus' authority is different.
He does not present one more interpretation that might eventually be replaced by a newer version. His Word stands forever.
Jesus Himself says:
"Heaven and earth will pass away, but my words will not pass away." (Matthew 24:35)
This is particularly relevant when we think about how people approach Christianity today.
Some believe that religion should evolve with the times. Ideas about sin, salvation, and God's character should be adjusted to fit modern preferences. What previous generations believed may be dismissed as outdated.
But if Jesus truly has authority, we cannot treat His teaching as something we are free to revise whenever it becomes inconvenient.
His authority also means that His message demands a response.
At the beginning of His ministry, Jesus proclaims:
"The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel." (Mark 1:15)
Repentance means recognizing that we are going in the wrong direction and turning away from sin. Faith means trusting in Christ and following Him.
These are not optional suggestions.
Imagine driving along Highway 1 toward your holiday destination when a police officer stops traffic because a forest fire is approaching. The officer is not offering an alternative route for you to consider. He is telling you to turn around because continuing forward would put your life in danger.
In a much greater way, Jesus calls us to repent and believe because He alone knows the way to life.
He declares in John 14:6:
"I am the way, and the truth, and the life. No one comes to the Father except through me."
To recognize the authority of Jesus is therefore not merely to admire His wisdom. It is to submit to His Word and obey His commands.
3. The Authority to Heal: Nothing Is Beyond His Power
From the synagogue, Jesus goes to the house of Simon and Andrew.
There He finds Simon Peter's mother-in-law lying sick with a fever. Jesus takes her by the hand, raises her up, and immediately the fever leaves her.
As evening comes and the Sabbath ends, people begin bringing their sick and demon-possessed relatives to Him.
Mark describes the scene:
"And the whole city was gathered together at the door. And he healed many who were sick with various diseases, and cast out many demons." (Mark 1:33–34)
Jesus' authority is not limited to teaching and calling disciples. He has authority over sickness, suffering, and even the spiritual forces of evil.
The demons recognize who He is. Interestingly, while people in the Gospels often question Jesus' identity, the demons know exactly who He is.
Yet Jesus does not allow them to speak.
Why?
Because the true meaning of His identity as the Christ must be understood in the light of the cross. Many people expected the Messiah to be a political deliverer who would remove Roman oppression. They did not understand that Jesus had come to accomplish something far greater: deliverance from sin and death through His suffering and sacrifice.
Jesus' authority would be fully revealed through the cross and resurrection.
There is another important comfort here.
Satan is not an equal and opposite power to God. As Martin Luther famously expressed in A Mighty Fortress Is Our God, even the devil remains under God's sovereign authority.
The forces of evil may be real, and suffering may be painful, but they are never beyond the sovereign rule of Christ.
And what about sickness?
The healing miracles remind us that Jesus has compassion and power over human suffering. Yet they do not mean that every Christian will be healed immediately in this present life.
We still experience illness, grief, and death. Some families go home to places where sickness has replaced joy with sadness.
We long for the day when these things will be no more.
The promise of Scripture is that this day will come. Revelation 21:4 tells us that God will wipe away every tear, and there will be no more death, mourning, crying, or pain.
Jesus has the authority to bring about that day.
Until then, we live with hope, trusting that our suffering is not outside His sovereign care.
As Luther's hymn reminds us:
"Though this world, with devils filled, should threaten to undo us, we will not fear, for God hath willed His truth to triumph through us."
Our confidence does not rest on the absence of suffering. It rests on the authority of Christ, who has already conquered sin and death.
4. Every Square Inch Belongs to Christ
So, who really runs your life?
We have seen Jesus enter three ordinary places: the workplace, the synagogue, and the home.
He calls fishermen in the middle of their workday. He teaches with authority in the place of worship. He heals the sick in a friend's house.
There is no area of life where His authority does not apply.
Abraham Kuyper famously expressed this truth:
"There is not a square inch in the whole domain of our human existence over which Christ, who is Sovereign over all, does not cry: 'Mine!'"
Think about what this means.
Our careers belong to Christ. Our families belong to Christ. Our finances, homes, relationships, ambitions, and daily decisions belong to Him.
Christianity is not simply one part of life, something we practise on Sunday before returning to our own priorities on Monday.
Christ is Lord over all of life.
And unlike an ordinary human ruler, His authority is not oppressive or arbitrary. He is the very One who came to serve, to suffer, and to give His life as a ransom for His people.
The One who commands us to follow Him is also the One who gave Himself for us.
Matthew 28:18 records His declaration after His resurrection:
"All authority in heaven and on earth has been given to me."
This is the foundation of Christian living.
We do not follow Jesus because He offers a few helpful suggestions for making life better. We follow Him because He is the risen Lord, the rightful King, and the One to whom all authority belongs.
The question, then, is not whether Jesus has authority over our lives.
He does.
The real question is whether we are willing to live under His loving authority.
We do not fit Jesus into the lives we want to build. We place our lives within the kingdom and the great story that He is writing.
What a wonderful place to be.
