This is new to me. Bear with me.

I think I understand what Paul meant when he said "I do what I dont want to do and I do not do what I want to do." This is what I am experiencing. Every morning I get up with this plan in mind what I will do this day. I fail another day. How do I do what I want to do not what I do not want to do???? In Lamentations 3 God's word says " your mercies are new every morning". I depend on Gods mercies being new every morning but ""' will those mercies run out???? I certainly hope not.
