Theologically, I don't promote the "Sinner's Prayer" - but just like the LORD's prayer in Matthew 6, its a great map to follow when coming to God. The following prayer isn't the "Sinner's Prayer" either, but rather a Prayer for Healing.
If your'e struggling with issues, perhaps this prayer may be of help....
Dear God, in the Name of Jesus:According to Romans 10:9 I confess with my lips that JESUS is Lord and in my heart I believe that You raised him from the dead. According to Luke 13:3 I repent of my past sins and I admit and confess that I have sinned and I believe that You are faithful and just to cleanse me from all unrighteousness. I call upon You, Lord JESUS to cleanse me from all sin and unrighteousness by Your Blood (1 John 1:7). And as Your word says in Romans 10:13 Everyone who calls upon the name of the Lord will be saved.
I confess and repent of occult practices such as (witchcraft, fortune telling, horoscopes, astrology, water witching, etc.)
I renounce all occult practices and satan and break all curses associated with those occult practices. According to Galatians 3:13 Christ purchased our freedom [redeeming us] from the curse [doom] of the Law [and its condemnation] by [Himself] becoming a curse for us, for it is written [in the Scriptures], Cursed is everyone who hangs on a tree (is crucified); Deut. 21:23.
I confess and repent of all sins listed in Deuteronomy 27 and 28 and break the curses associated with these sins.
I confess and repent of my iniquities and my father's iniquities according to Leviticus 26:40 and I break the curses associated with these iniquities.
I break and loose myself from all evil soul ties with my mother, father, brother, sisters, spouses, former spouses, former sex partners, pastors, churches, friends, etc.
Lord JESUS: I forgive my mother, father, brothers, sisters and anyone else who has ever hurt me, including all whites, blacks, indians, mexicans, etc. Matthew 6:15, 18:21, 22, 35; Luke 11:4 (Lord's prayer).
I break and loose myself and my family from all curses that have been and are being placed upon me and my family, including any demons being sent to us: curses of witchcraft, physic thoughts or prayers, ungodly intercessory prayers; all words spoken in anger, hurt, sorrow, or bitterness; all incense being burned for or against us, in JESUS' name. AMEN!
