Imagine a father who, every time you get together, requires you to tell him about ALL your recent mistakes & failures before going into any other conversation. And if you don't do so He will have nothing to do with you. Who wants to even approach a father who requires every conversation start with focusing on your faults?
That was how I & many others were taught to pray to our heavenly Father. We were told, "Confess your sins when you start the prayer or God will not hear you." This idea of God is the complete opposite of grace. It pictures him as letting any & every conceivable negative thing immediately stand between you & him because he is so impatient & offendable.
I thank you true Father that you are not a graceless grump who is always looking for an excuse to ditch or demean his children. I thank you that You love us with humble gentleness & not with harsh egotism.
