If Jesus has forgiven you, there will be some changes in your life. This isn’t a comprehensive list but I believe it covers some basics:
2 Corinthians 5:17, Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
Your desires will change-
You’ll have a desire to attend church, read your Bible, be around other Christians, to please the Lord and not man, to share your faith...
Your duties will change-
You’ll want to help others for nothing, coming to church will be a priority, giving the Lord His tithes and offerings will be cheerful thing to do; not a chore.
Your destination will change-
No more going to the bar, the liquor store, the whore house, the casino, the sweepstakes buildings, the drug dealers house.... Hey- if Jesus has forgiven you, you’ll be on your way to Heaven and you’ll want to be familiar with what Heaven is going to be like!
Think about what Paul said to the Christians in Rome:
I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service. And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God. Romans 12:1-2
