A faith of devils, a mere intellectual faith, a man may have without love, but not that faith which saves. Love cannot usurp the office of faith. It cannot justify. It does not join the soul to Christ. It cannot bring peace to the conscience. But where there is real justifying faith in Christ, there will always be heart-love to Christ. He that is really forgiven is the man who will really love (Luke 7:47). If a man has no love to Christ, you may be sure he has no faith.
