This quote was on John 3: 22-36 speaking of John the Baptist. Remember he was the forerunner of Christ. It might be well to read these verses then the quote but what ever you decide to do, this is an outstanding thought to apply to our lives.
DA 179-180 "Those who are true to their calling as messengers for God will not seek honor for themselves. Love for self will be swallowed up in love for Christ. No rivalry will mar the precious cause of the gospel. They sill recognize that it is their work to proclaim, as did John the Baptist. "Behold the Lamb of God, which taketh away the sin of the world." John 1:29.
So with the followers of Christ. We can receive of heaven's light only as we are willing to be emptied of self. We cannot discern the character of God, or accept Christ by faith, unless we consent to the bringing into captivity of every thought to the obedience of Christ. All who do this the Holy Spirit is given without measure. In Christ 'dwelleth all the fullness of the Godhead bodily, and in Him ye are made full." Col. 2:9,10."
Are you willing to let self be swallowed up in love for Christ? Surrender of self is the hardest thing for us to let go of. But we must let go of self and let God have full control of our life. It may seem a bit scary to some but it really smooths out all of life's problems and gives the Christian true peace. I need that peace and want it. My life has been a bumpy ride and it's time for a smooth one in Christ. It doesn't mean there will be no more trials, it just means that Christ is at the helm and is responsible for getting us through them unscathed and to be a stronger person in Him. Grandma Joan
