The formula for doing the right thing includes seeking God, avoiding impulse and fleeing from temptation. Pray and prioritize all the things in your life.
Godly sorrow works for repentance, but the sorrow of the world works for death. Submit your thoughts and emotions to God so He can really know how you feel.
Don’t take it personally if someone hates you because you’re a Christian. Hearts that turn away from God react this way. Say yes to God’s will and be sure that when the truth of God comes to you that you don’t quench it. Everyone makes mistakes and you will always remember them. But repent to God and things will be made anew.
