The life of Christianity consists very much in our love to Christ. Without love to Christ, we are as much without spiritual life—as a carcass when the soul is fled from it is without natural life. Faith without love to Christ is a dead faith, and a professor without love to Christ is a dead professor, dead in sins and trespasses. Without love to Christ we may have the name of Christians—but we are wholly without the nature of Christians. We may have the form of godliness—but are wholly without the power of godliness. “Give me your heart!” is the language of God to all people, Proverbs 23:26; and “Give me your love!” is the language of Christ to all His disciples.
