Below is an example of a prayer of salvation if you find yourself wondering what you could possible pray. I’m not recommending that you use the same words, but for it to only be of a guide for you to find your own words from your heart, to our Lord.
Father God, I recognize that I have not lived my life for You. I have been living for myself and that is wrong. I need You in my life; I want You in my life. I acknowledge the completed work of Your Son Jesus Christ in giving His life for me on the cross at Calvary, and that You Father God, raised Him from the dead. I long to receive the forgiveness you have made freely available to me through this sacrifice. Come into my life now, Lord. Take up residence in my heart and be my king, my Lord, and my Savior. From this day forward, I will no longer be controlled by sin, or the desire to please myself, but I will follow You all the days of my life. Those days are in Your hands. I ask this in Jesus’ precious and holy name. Amen.
