"“Thou therefore, my son,” Paul continued, “be strong in the grace that is in Christ Jesus. And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also. Thou therefore endure hardness, as a good soldier of Jesus Christ.” [ 2 Timothy 2:1-3 .] GW 108.1"
"Thou therefore, my son, be strong in the grace that is in Christ Jesus. And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also. Thou therefore endure hardness, as a good soldier of Jesus Christ."
Ellen White directly references 2 Timothy 2:1-3 in this passage.
"The true minister of God will not shun hardship or responsibility. From the Source that never fails those who sincerely seek for divine power, he draws strength that enables him to meet and overcome temptation, and to perform the duties that God places upon him. The nature of the grace that he receives, enlarges his capacity to know God and His Son. His soul goes out in longing desire to do acceptable service for the Master. And as he advances in the Christian pathway, he becomes “strong in the grace that is in Christ Jesus.” This grace enables him to be a faithful witness of the things that he has heard. He does not despise or neglect the knowledge that he has received from God, but commits this knowledge to faithful men, who in their turn teach others. GW 108.2"
"Thou therefore, my son, be strong in the grace that is in Christ Jesus."
EGW directly quotes 2 Timothy 2:1, making it an explicit allusion. The surrounding context in EGW's writing further elaborates on the idea of being strong in the grace of Christ Jesus.
"I can do all things through Christ which strengtheneth me."
Both passages address the source of strength for ministry. Philippians 4:13 states that one can do all things through Christ who strengthens, while EGW describes drawing strength from a source that never fails. The theme of divine empowerment for service is present in both.
"In this his last letter to Timothy, Paul held up before the younger worker a high ideal, pointing out the duties devolving on him as a minister of Christ. GW 108.3"
"Let no man despise thy youth; but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity."
Both passages relate to Paul's instructions to Timothy. 1 Timothy 4:12 encourages Timothy to be an example, while EGW mentions Paul holding up a high ideal and pointing out duties. The shared theme is guidance and instruction for a younger minister.
