For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light. Ephesians 5:8.
(TDG 135.1)
He who commanded the light to shine out of darkness sheds light into the mind of every one who will properly behold Him, loving Him supremely, showing unswerving faith and trust in Him. His light shines into the chambers of the mind and into the soul temple. The heart is filled with the light of the knowledge of the glory that shines in the face of Jesus Christ. And with this light comes spiritual discernment....
(TDG 135.2)
Yielding willingly to the evidence of truth, and walking in the light that shines in our pathway, we receive still greater light. Through the power of the manifestation of divine glory, we constantly advance in spiritual understanding.
(TDG 135.3)
Christ’s knowledge of truth was direct, positive, without a shadow. The closer the acquaintance a man has with Jesus Christ, the more careful he will be to treat his fellow men respectfully, courteously, righteously. He has learned of Christ, and he follows His example in word and action. By faith he is united with Christ. “We are labourers together with God” (1 Corinthians 3:9)....
(TDG 135.4)
Christ’s prayer was for unity among His followers. This unity is the evidence that is to convince the world that God sent His Son to save sinners. We serve Christ by revealing true, pure, holy love for one another. Those who are chosen to connect with the Lord’s institutions are to be devoted, self-denying, self-sacrificing men, living not to please themselves, but to please the Master. These are the men who will do honor to the Lord’s institutions.
(TDG 135.5)
A knowledge of God and of Christ is positively essential to salvation. We lose much every day that we do not learn more of the meekness and lowliness of Christ. Those who learn of Christ obtain the very highest class of education. Through faith and dependence on the saving grace of Christ, they increase in knowledge and wisdom. They love and praise the Saviour....
(TDG 135.6)
Those who are saved must in this life make it their daily business to receive grace from God, not to hoard in selfishness, but to impart for the blessing of those connected with them, to aid them in obtaining an education in spiritual things.—Letter 191, May 6, 1901, to W. L. Hoover.
