My interpertation of the lyrics are someone who is having trouble keeping with God. His mind is his own worst enemy, because what others have told him about what is truth is in his head, and he can't make up his mind. And the lyrics seem like the singer is telling the person to remember what Christ has given them, and to forget about what others say.
