What is the Almighty, that we should serve him? and what profit should we have, if we pray unto him?
(Cf. Jeremiah 2:20, "I will not serve" (God), margin; Proverbs 30:9; Exodus 5:2, Pharaoh, "Who is the Lord, that I should obey His voice? I know not the Lord.")
What profit - (Job 35:3; Malachi 3:14, "It is vain to serve God: and what profit is it that we have kept His ordinance?" Psalms 73:13). Sinners ask not what is right, but what is for the profit of self. They forget, 'If religion cost self something, the want of it will cost self infinitely more.'
Pray unto him - literally, 'apply to Him with prayer.'
