"All" my heart? "All" I do? God can't actually mean "All". He surely is referring only to the things I can't do or don't want to do. Let's face it ... I am extremely competent and talented so I should be able to depend on myself most of the time and in 99% of what I do. God is busy. He doesn't deal with the "little stuff". God must only be referring to the REALLY hard stuff, like midterm exams or first dates or when my car won't start and I am late for an appointment. "Lord, help this dang thing start right now!" God actually doesn't care about your exam, your dating life or your car. God DOES care about you and ALL of you, and ALL that you care about.
Lord, help me to realize that You care so much about me that You want me to be ALL IN for you, just like You want me to allow You to be ALL IN with me.
