Galatians 2:16-18 English Standard Version
16 yet we know that a person is not justified[counted righteous] by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified.
17 But if, in our endeavor to be justified in Christ, we too were found to be sinners, is Christ then a servant of sin? Certainly not! 18 For if I rebuild what I tore down, I prove myself to be a transgressor.
The lyrics are “I did it my way!” Those are the words of worldly pride. There is no humility in them. We should be people who endeavor to be justified by Christ. We should look at endeavor as a course of action on our part, separate from what God has done to justify us.
Verse 18 above is very clear that once we are born again, we should not go about building this new life in Christ after the model of our old life of sin. Doing it our way got us to a position where we needed Christ to save us. Why should we live once again to serve our egos by making the same mistakes again and again?
Isaiah 43:19 English Standard Version (ESV) Behold, I am doing a new thing; now it springs forth, do you not perceive it? I will make a way in the wilderness and rivers in the desert.
God declares that He is doing the work and that we are to perceive what He is doing.
Hebrews 12:6 English Standard Version (ESV) For the Lord disciplines the one he loves, and chastises every son whom he receives.
When our perceptions are wrong, He will correct our vision.
