My limitations help develop my Christian character. They also seem to help deepen my worship. As we admit to our limitations and weaknesses, and turn to God for help to overcome them, we affirm God's strength and power in us. That said, His power is truly shown in my weakness.
Experience had taught me that I am capable of little. And the things I do seem to be capable of I am also capable of screwing up. So unless the Lord shows up to help me make something good or do something good, I have little hope that it could turn out well.
