God doesn't want you to be perfect

In fact, as fallible human beings, he knows that we are incapable of perfection.  What he wants us to do, I believe, is the best that we can.  Then we we fail, we should pick ourselves up, ask forgiveness of Him and anyone else we have failed, and keep on trucking.  What he does not want us to do is think of all the ways that we are going to screw up, work ourselves into a puddle of guilt, and get nothing accomplished.  As long as we are doing our best and putting one foot in front of the other while trusting in Jesus Christ, we are doing our part, and we can trust Him to do His.
