You cannot change yourself

We have spent considerable time talking about character. We have seen why it matters. We have seen how sin damaged it. We have seen how Jesus revealed the character of God. We have examined the practical tests that expose what is inside us. But now we come to a crucial question: How do we actually change?

If character is so important, how do we develop righteous character? The natural human response is: Try harder. Make better decisions. Control your temper. Stop the bad habits. Be more patient, more loving, more disciplined, more obedient. There is certainly a place for disciplined choices. But if that is where we stop, we have misunderstood the gospel. The Christian life is not fundamentally a self-improvement programme. We cannot manufacture Christ’s character by ourselves. Jesus said it plainly: “Without Me you can do nothing” (John 15:5). Nothing. Not “a little less.” Not “some things.” Nothing. That is a humbling truth.

Peter: “I will never be made to stumble”

Peter’s story shows how real that truth is. On the night before the cross, Jesus told His disciples that they would all fall away. Peter answered with complete confidence:

Even if all are made to stumble because of You, I will never be made to stumble.

He meant it. He was sincere and brave, and within hours he had denied Jesus three times (Matthew 26:69-75). The problem was not Peter’s sincerity. It was that he was relying on himself. After the resurrection, Jesus restored him on the shore of Galilee and asked him three times, “Do you love Me?” Peter no longer said, “I will never.” He said, “Lord, You know all things; You know that I love You” (John 21:17). The man who spoke on the day of Pentecost was not a man who had learned to try harder. He was a man who had learned to depend on Christ.

The problem with trying to be good enough

There is something deeply appealing about self-reliance. We like to believe that if we simply work hard enough, we can fix ourselves. But sin is deeper than behaviour. As we saw in chapter 7, the problem is in the heart, and we cannot cure the heart by pruning the fruit. We can sometimes control individual behaviours through determination, fear, social pressure or habit. But only God can transform the heart from which those behaviours come.

The will and grace

There is another truth we must hold together. We cannot transform ourselves by willpower alone, but neither does grace turn the human being into a passive spectator. We have already met Paul’s words at the end of Part Five: “Work out your own salvation with fear and trembling; for it is God who works in you both to will and to do for His good pleasure” (Philippians 2:12-13). Notice the balance. The believer is called to respond, while God supplies the enabling power. Grace does not make the will irrelevant; grace restores the will so that it can be surrendered to God.

We may not be able to command every emotion to disappear or prevent every temptation from arising. But we can bring our will to Christ. We can say, “Lord, I choose Your way rather than my own.” We can refuse to nourish a sinful desire, seek the help of the Holy Spirit, and continue to abide in Christ. This is not salvation by human effort. It is cooperation with divine grace. We surrender; God transforms. We choose to abide; Christ supplies the life. We respond in faith; the Holy Spirit produces the fruit.

Nicodemus and the new birth

Nicodemus was a religious man. He was educated, respected and a leader. He knew Scripture. Yet when he came to Jesus by night, Jesus told him something he did not expect:

Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God.

Nicodemus was thinking about behaviour. Jesus was talking about transformation. Nicodemus needed more than additional knowledge. He needed a new life, and Jesus explained that it is the work of the Spirit:

The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit.

That is still true today. A person can know more theology and remain proud. A person can know more Scripture and remain unforgiving. A person can understand prophecy and remain selfish. A person can attend church for decades and still need the transforming work of the Holy Spirit. Knowledge is important. Truth matters. But truth must reach the heart.

God does what we cannot do

The gospel is not God standing at a distance saying, “Make yourself righteous, and then I will accept you.” The gospel is God coming to us in Christ and saying, “You cannot save yourself. Come to Me.”

Come to Me, all you who labor and are heavy laden, and I will give you rest. Take My yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls.

There is both rest and learning. Grace and transformation. Acceptance and discipleship. Forgiveness and obedience. Christ does not merely remove our guilt. He teaches us to walk with Him.

Dependence is not weakness

Because we cannot transform ourselves, we must learn to depend upon God. James gives a simple promise:

If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him.

Prayer is part of that dependence. When we do not know how to respond, we can ask for wisdom. When we are weak, we can ask for strength. When we are tempted, we can ask for deliverance. When we have failed, we can confess and return to Christ. The transforming work belongs to God, but we must willingly remain in His hands. The question is not merely, “How can I become a better person?” It is, “Am I allowing Christ to make me a new person?”

Transformation begins in the mind

Paul gives us a remarkable picture of Christian transformation in Romans 12. He begins with God’s mercy and moves to surrender:

I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service.

Christian character does not begin with outward performance. It begins with surrender. We place ourselves before God, not because we have already become what we should be, but because we recognise that His mercy has made a new life possible. Then comes the instruction we met in chapter 8: “be transformed by the renewing of your mind” (Romans 12:2). The order matters. God is not merely asking us to change our behaviour while leaving our thinking untouched. He works from the inside outward.

The renewed mind begins to see differently. It evaluates success differently. It responds to conflict differently. It thinks about other people differently. It begins to recognise sin for what it is and righteousness for what it is. And as the mind is renewed, choices begin to change. Paul says that the renewed mind becomes able to “prove what is that good and acceptable and perfect will of God.” The transformed life becomes increasingly aligned with the will of the One who is transforming it.
