I am a Christian, and I still struggle with sin.
Daily.
Like the Apostle Paul, I do sinful things that I don’t want to do, and I don’t do the things I know I ought to do (Romans 7:18-20). Such is the life of a Christian. Through the work of Christ, we’ve been made righteous in the eyes of the Father and we’ve been filled with the Holy Spirit, who gives us the desire and ability to obey God’s Word and do what is right. But all of us, even the godliest of saints, are still sinners. We still mess up and make mistakes. We hurt and offend people, and we disobey what’s written in the Scriptures. We say and do the wrong things, even if we have the best of intentions.
Thankfully, God doesn’t leave us this way. He doesn’t just save us and say sayonara, leaving us to fend for ourselves and figure out how to behave on our own until Jesus returns. No, God actively works in and through us every single day to make us more and more like Him through a process called sanctification.
