We have every encouragement that if we daily surrender our wills to God the promise will be fulfilled, “And of his fulness have all we received, and grace for grace” (John 1:16). Every revealing of the grace of Christ in our behalf is for us. We are to reveal His grace in our lives, in thought, word, and deed.... We are to represent the mercy, the love, and the power of Christ—the power that He has given us....
Were it not for the power received through Christ we would have no strength. But Christ has all power. “Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. Go ye therefore, and teach all nations, ... and, lo, I am with you alway, even unto the end of the world.” Here is our power, our comfort. Of ourselves we have no strength. But He says, “I am with you alway,” helping you to perform your duty, guiding, comforting, sanctifying, and sustaining you, giving you success in speaking words that will draw the attention of others to Christ and awaken in their minds the desire to understand the hope and meaning of the truth, turning them from darkness to light....
It is a wonderful thought that human beings can speak the word of God, in simple words of comfort and encouragement. The humblest instruments will be used of God to sow the seeds of truth, which may spring up and bear fruit, because the one in whose heart they were sown needed help—a kind thought, a kind word, made effective by the One who has said, “Lo, I am with you alway.”
To us also the promise of Christ’s abiding presence is given. The lapse of time has wrought no change in His parting promise. He is with us today as truly as He was with the disciples, and He will be with us “even unto the end.” ...
He finds His faithful ones, and holds communion with them, encouraging and strengthening them. And angels of God, that excel in strength, are sent forth by God to minister to His human workers who are speaking the truth to those who know it not. HP 188
Our self-confidence would vanish, did we talk less and pray more. Pr 213
