1 john 3
19 By this we shall know that we originate with the truth, and we shall assure our hearts before him 20 as regards whatever our hearts may condemn us in, because God is greater than our hearts and knows all things.

I think that this is just a great scripture. It tells us that Jehovah is greater then our hear ts. When we get down on ourselves and feel that we don't deserve the loving kindness of Jehovah. WHen our heart condemns us that Jehovah knows our deepest inside motivation and person; he knows all things. We must never ever think that we know more then Jehovah. He loves us and we are worth loving
