Colossians 2:6
And now, just as you accepted Christ Jesus as your Lord, you must continue to follow him.

What does it mean to follow Christ? He has to be my Lord today the same way he was when I confessed him as Lord.

And what was that? When I accepted Christ I told him I was done with this world and every deceptive thing it offered me. I told him I hated sin and was sick of it ruining my life. I told him I knew I offended him every day of my life, and indeed my life had been built on-and consisting of nothing but-rebellion and willful ignorance. I cried out that I was sorry and done, and that now I’d live my life in totality, every minute of every day, for him alone. What else does it mean to repent of your sins and to believe the gospel, that Christ died for sinners?

And the lie that you start off hot for God when you accept him, then slowly level out to normalcy? It’s just that, a lie. Over time those I know who have come to know the Lord have grown slowly hotter for Christ,  because he will spit the luke-warm out of his mouth and those in whom he has began a good work, he will bring it to completion.
