What Can I do?

What happens when a person constantly thinks about sinning against God? When the fear of it overtakes their life? When it becomes less of a conscious state and more of a paralyzing fear? I have come to this point... and I need help!

Lord, you know my heart... please help me. Lord to me how to Live by Grace.... For you didn't die for the perfect.. I am not perfect. Teach me to step daily in your love and forgiveness.. and If i do fall, you will pick me up!

"I have hidden your word in my heart that I may not sin against you"~ Psalm 119:11
