Jesus Christ doesn’t just give us truths; he is the truth. Jesus Christ is the prophet to end all prophets. He gives us hard-copy words from God, truths on which we can build our lives, truths we have to submit to, truths we have to obey, and truths we have to build our lives on, but he himself is the truth.
Timothy KellerTo take a person out of slavery takes an instant. To take slavery out of a person takes a process.
Timothy KellerUnless we believe the gospel, we will be driven in all we do-whether obeying or disobeying-by pride ('self-love') or fear ('of damnation'). Apart from 'grateful remembering' of the gospel, all good works are done then for sinful motives. Mere moral effort may restrain the heart, but does not truly change the heart. Moral effort merely 'jury rigs' the evil of the heart to produce moral behavior out of self-interest. It is only a matter of time before such a thin tissue collapses.
