"My brethren and sisters, let us not become weary in well-doing. During His earthly ministry, Christ traveled on foot from place to place. Wearied, as He ofttimes was, His human nature taxed to the uttermost, yet He was ever ready to heal all who came unto Him, and to teach them the way of life eternal. Though often physically exhausted, He left not His work. There was a world to be saved. He made every sacrifice possible, in order that light and truth might shine forth. 9T 87.1"
"And let us not be weary in well doing: for in due season we shall reap, if we faint not."
Both passages encourage perseverance in doing good and not becoming weary. The EGW passage uses Christ's example to illustrate this principle, while Galatians 6:9 states the principle directly. The connection is strong and relevant.
"The Lord God of Israel desires us to link up in holy union with Himself and exercise the living faith that works by love and purifies the soul. He desires that we shall be a working corps of laborers endowed with adaptability for His service, and to such He promises power to win a glorious victory for Him. 9T 87.2"
"That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me."
Both passages emphasize unity and being connected with God. John 17:21 speaks of the unity of believers with God and each other, while the EGW passage speaks of linking up in holy union with God. The connection is thematic and meaningful.
"Sanitarium, California, July 10, 1908. ***** The men who stand as leaders in any part of the solemn work of the last gospel message must cultivate and cherish broad views and ideas. It is the privilege of all who bear responsibilities in the work of the gospel to be apt learners in the school of Christ. The professed follower of Christ must not be led by the dictates of his own will; his mind must be trained to think Christ's thoughts and enlightened to comprehend the will and way of God. Such a believer will be a follower of Christ's methods of work. 9T 87.3"
"For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ."
Both passages discuss having the mind of Christ. 1 Corinthians 2:16 explicitly states "we have the mind of Christ," and the EGW passage speaks of training the mind to think Christ's thoughts.
