Q.2: Ought everyone to believe there is a God?
A. Everyone ought to believe there is a God; and it is there great sin and folly who do not.
“And without faith it is impossible to please Him, for he who comes to God must believe that He is and that He is a rewarder of those who seek Him” (Hebrews 11:6; NASB).
“The fool has said in his heart, ‘There is no God.’ They are corrupt, they have committed abominable deeds; there is no one who does good” (Psalm 14:1; NASB).
