“Teach me to do Your will, For You are my God; Your Spirit is good. Lead me in the land of uprightness. Revive me, O LORD, for Your name’s sake! For Your righteousness’ sake bring my soul out of trouble.”
Psalms 143:10-11 NKJV
This is a prayer of David. He knows that he is not able to do good on his own, but with the Lord’s help he can. With the Lord’s help he can do anything… But his prayer is explicit – it is for His righteousness’ sake. We need His help for His glory.
