When a person is truly sincere with God, He will do a work that cannot be comprehended. Humans are very limited and God understands that. When serving God if we lift a finger He gives a hand. When we take a step He walks a mile. When we are totally at a loss for words or actions He will work out the whole thing. We never have to worry how God will bring it to about. His love accomplishes all things.
Trust in the Lord with all your heart
and lean not on your own understanding;
in all your ways submit to Him,
and He will make your paths straight.
