I was ministering to someone and wrote this prayer for her. I had hoped to write it as a prayer that someone who was seeking God could pray as a non-Christian (what her state seemed to be) but would also be appropriate for her if she already knew God.
Oh God most high and holy, I understand that you are worthy to be praised with my every breath, and loved with all the love that I am able to offer and more besides. Occupy the throne of my heart, Take full possession of my life and reign supreme in me. Tear aside every sin in my life and make yourself my highest love. Don't allow my vile passions and lusts to resist your Spirit in this work Show me your mighty power in this way and make me yours forever. I am learning what it means, that I am dead in my sins and iniquities. I have done so many things that I know are grievous to you. More than that, I have not loved you as I should: with all of my heart, soul, and mind. I confess all of these sins before you. I come to you knowing that I have no right, of myself, to do so; but that you have purchased my right to make this request to you you welcome poor sinners to come to you and find rest and freedom. So I ask: please free me from my sins, please give me rest in you. I understand that your son, Jesus Christ, has died to save wicked people, like me, from their sins. He took on the sins of the world, that hopeless sinners might be declared righteous and holy. Help me to understand, that righteousness is hid with Christ on high; that I am not more righteous when I am living rightly nor am I less righteous when I am living sinfully; but if I trust in my own good behavior, I am completely wicked before you; but if I trust in Christ, I am as righteous as you are because I trust in your holiness applied to me on the cross. and this righteousness is the same yesterday, today, and forever. Then teach me to live on you and to live for you. Guide me down paths of righteousness that I might live all of life for your namesake. Teach me how to live as Christ lived, that I might resemble you. I throw myself to your care. I know that I cannot save myself, I have tried and only found failure. Great God in heaven, save me.
