I love hearing testimonies about what God has done in people's lives. Jesus came to set captives free from sin. Did you know that your testimony doesn't end the day you were born again? It begins there.
Can you imagine how strange it would be to hear someone say something like, "I was addicted to drugs, then I got saved and I'm still totally addicted to drugs but I am forgiven." Yet, that's how some people professing to be Christians live...stuck in bondage to sin.
Romans 6:14-16 says, "Sin is no longer your master, for you are no longer subject to the law, which enslaves you to sin. Instead, you are free by God's grace. So since God's grace has set us free from the law, does this mean we can go on sinning? Of course not! Don't you realize that whatever you choose to obey becomes your master? You can choose sin, which leads to death, or you can choose to obey God and receive his approval."
So, God's grace is what saves the Christian and it is also what changes the Christian.
Galatians 3:3 says, "Have you lost your senses? After starting your Christian lives in the Spirit, why are you now trying to become perfect by your own human effort?"
The secret to overcoming sin takes the same humble heart as being born again. If you try to make a bunch of rules in order to avoid sin, or promise God you will never do it again, you might be able to do well for a while, but you will end up prideful in your own abilities and devastated when you fall. Peter the apostle promised Jesus he would never deny Him, then fell asleep when Jesus told him to pray that he wouldn't fall into temptation, and ultimately denied Him three times.
The key is simple really. Just follow these three steps:
1) Admit that you can't change and overcome the sin on your own. (Humility is the one prerequisite to grace.)
2) Confess that you want God to change you. (He won't force you)
3) Pray that you do not fall into temptation and put God's word into your heart.
What's your cardboard testimony?
