Father we pray for this dear person. Lord you know their life. They have asked for prayer because of sin in their life. Father fill this prayer requester's heart with your holy spirit, and bring them to the foot of Calvary's cross. Show them the one who died to forgive them of their sin, no matter how bad it has been. Let them get a clear understanding of the love that drew salvation's plan, and of the grace that brought it down to man.
Lord we have all sinned and fallen short of God's glory. But you made a way through the death and resurrection of your son Jesus Christ who took the punishment that we deserved so that we may be set free from the punishment of sin and death. Dear brother or sister in Christ, confess your sin before God and ask for his forgiveness. It is there waiting for you if you will ask for it now. For it was already purchased for you over 2000 years ago. Christ was nailed to a cross where he bled and died for you and for me. Not because we were worthy and righteous and good. No... we were not, he died for us while we were still yet sinners. He died for an undeserving, rebellious and wicked humanity. He loves you and died for you. Go to him in prayer with a contrite heart and you will be forgiven. Get into a good bible-based church, read his word the holy bible and he will change your life, I promise, but more importantly HE PROMISES.
Lord we hold this person up before you this day and pray for their soul. May they come to know your love for them and your favour upon their life as they turn to you for deliverance from sin and guidance throughout the rest of their life. In Jesus name we pray amen.
