The title of this teaching is probably decoupaged or needlepointed on the wall of many homes, and for good reason. It is what our Lord Jesus Christ showed us by his sterling example of self-sacrifice.
This teaching could be sub-titled The Power of Love, because godly love is the greatest force there is to bring to pass the will of God on earth. We focus on the Greek word agape and center this teaching primarily in the fabulous epistle of 1 John.
Each of us is called to love as Jesus loved, and he is ready to teach us how to do that, if we are willing to walk the path of love he blazed for us. The more we do, the more our hearts sing with his joy and his peace.
