God wants us to walk—live our lives—by faith, but our pride and vanity frequently get in the way. Critically, pride causes us to reject God and His Word.
Our human nature is pure vanity with a heart that is desperately deceitful and wicked, motivated by self-centeredness, a deadly combination for producing sin.
Christ severely criticizes the church of Pergamos for the doctrine of Baalam and idolatry. Nevertheless, to those who overcome, He will grant eternal life.
