Acts 28:31 - Boldly and without hindrance he (Paul) preached the kingdom of God and taught about the Lord Jesus Christ.
What kind of legacy are you leaving behind.? When you leave this earth what will people remember you for? Paul had done a lot of bad things in his life. He grew up in the teachings and doctrines of a Pharisee, and once he became an adult he strongly opposed Christians.
Throughout his first few years in the religious world he heavily persecuted the church, throwing Christians in jail and even putting some of them to death. He didn't start off well, but then Jesus got a hold of him.
Paul changed and devoted himself to preaching the kingdom of God and teaching about Jesus. Now, at the end of the book of Acts, as Luke is concluding his testimony of the early Christians, he makes this statement about Paul: “Boldly and without hindrance he preached the kingdom of God and taught about the Lord Jesus.” That’s what Paul is remembered for; his legacy. Despite all he did in the past.
God is saying that to us as well. It doesn't matter what you've done or where you come from. What matters is what you are doing now and where you are going. God does not want someone who’s “perfect” and already has it all worked out. He wants you. Come as you are. Let Jesus cleanse you and renew you.
Surrender your life to Him and He will work in you. You do not have to be known for what you've done, but for what God has done in you. Zig Ziglar put it like this “You have made some mistakes, and you may not be where you want to be, but that has nothing to do with your future.” Let God create a legacy through you.
