The great lesson of Christ
Beloved, if God so loved us, we also ought to love one another. 1 John 4:11
The great lesson that Christ taught by his life and example was that of unity and love among brethren. This love is the token of discipleship, the divine credentials which the Christian bears to the world. “By this shall all men know that ye are my disciples, if ye have love one to another.” Love to God and man must be an inwrought principle in the soul; for there is no other way that the Christian can become a “partaker of the divine nature, having escaped the corruption that is in the world through lust.” {The Review and Herald par. 2}
