So you are no longer a slave, but a son; and since you are a son, God has made you also an heir. Galatians 4:7 (NIV)
This remarkable change has already happened in your life if you are a Christian believer. You were a slave. Now you are a son.
The gospel sets you free. God has embraced you, in Christ, who died to redeem you. He has made you a new creation in Christ by the Spirit who lives within you. Grasping the gospel means believing that these things are true for you in Christ.
Here is something very strange. There are many people who believe themselves to be Christians, but constantly tell themselves that they are slaves! “I have this sin that I just can’t get over. I was made like this. It’s the way I am.”
Now when you think like that or talk like that, you are saying that you are a slave to your sin. When you say, “I am a slave,” you are denying the gospel. You are not living by faith in the Son of God who loved you and gave Himself for you. There’s only one way to live the Christian life and that is by believing the gospel, believing that what God promises in Christ is true for you.
Victory over sin begins with believing the gospel. You will be transformed by the renewing of your mind. You will know the truth and the truth will set you free.
Is there a habitual sin in your life that you think you cannot overcome? Will you trust in the promise of Christ today that you are no longer a slave to that sin?
