How to pray if you have never prayed before:

“God be merciful to me a sinner, and make me do and know and believe in Jesus Christ: for I see, that if his righteousness had not been, or I have not faith in that righteousness, I am utterly cast away. Lord, I have heard that thou art a merciful God, and hast ordained that thy Son Jesus Christ should be the Saviour of the world; and moreover, that thou art willing to bestow upon such a poor sinner as I am, (and I am a sinner indeed) Lord, take therefore this opportunity , and magnify thy grace in the salvation of my soul, through thy Son Jesus Christ. Amen” (John Bunyan).

And keep on praying, on your knees, until God answers you.
