He that watereth shall be watered also himself. Proverbs 11:25. LHU 187.1
The teaching of Christ was the expression of an inwrought conviction and experience, and those who learn of Him become teachers after the divine order. The Word of God, spoken by one who is himself sanctified through it, has a life-giving power that makes it attractive to the hearers, and convicts them that it is a living reality. When one has received the truth in the love of it, he will make this manifest in the persuasion of his manner and the tones of his voice. He makes known that which he himself has heard, seen, and handled of the Word of life, that others may have fellowship with him through the knowledge of Christ. His testimony, from lips touched with a live coal from off the altar, is truth to the receptive heart, and works sanctification upon the character. LHU 187.2
And he who seeks to give light to others will himself be blessed. “There shall be showers of blessing.” “He that watereth shall be watered also himself.” God could have reached His object in saving sinners without our aid; but in order for us to develop a character like Christ's, we must share in His work. In order to enter into His joy—the joy of seeing souls redeemed by His sacrifice—we must participate in His labors for their redemption. LHU 187.3
Nathanael's first expression of his faith, so full and earnest and sincere, fell like music on the ears of Jesus. And He “answered and said unto him, Because I said unto thee, I saw thee under the fig tree, believest thou? thou shalt see greater things than these.” The Saviour looked forward with joy to His work in preaching good tidings to the meek, binding up the brokenhearted, and proclaiming liberty to the captives of Satan. At thought of the precious blessings He had brought to men, Jesus added, “Verily, verily, I say unto you, Hereafter ye shall see heaven open, and the angels of God ascending and descending upon the Son of man.” LHU 187.4
Here Christ virtually says, On the bank of the Jordan the heavens were opened, and the Spirit descended like a dove upon Me. That scene was but a token that I am the Son of God. If you believe on Me as such, your faith shall be quickened. You shall see that the heavens are opened, and are never to be closed. I have opened them to you. The angels of God are ascending, bearing the prayers of the needy and distressed to the Father above, and descending, bringing blessing and hope, courage, help, and life, to the children of men. LHU 187.5
The angels of God are ever passing from earth to heaven, and from heaven to earth.... And thus Christ is the medium of communication of men with God, and of God with men (The Desire of Ages, 142, 143). LHU 187.6
