BELIEVE is OBEY from the “HEART”.
Believe is obedience. Faith is obedience. Belief and Faith are the same thing in the Lord Jesus Christ. Only He can see in your heart — obedience as an act of work just to say you did it — or obedience from a truthful, loving heart.
(John 14:21, James 1:22, Isaiah 1:18-20).
