If You are a Christian
If you are a Christian living in sin, you must put an end to it today. Tomorrow will be too late! Just say to God from your heart that you are sorry for what you have done in disgracing the name of God and Jesus to all those around you, through them seeing you living in sin. Ask Jesus to come into your heart and make you clean. God never gets tired of forgiving - it doesn't matter what you have done in the past, but now go and do not sin anymore!
If you have never prayed to receive the Holy Spirit, then pray everyday without ceasing. He will replace the emptiness inside of you with peace, love and joy. He will guide you in all truth, comfort you in your times of distress and help you say no to sin.
"Many who carry the name of CHRISTIAN are overcome by greed, fornication, drunkenness, and a pursuit for great wealth. Those who live in defilement and meditate upon evil things will have no escape..."
