"The Lord bids us, “Charge them that are rich in this world” that they trust not “in uncertain riches, but in the living God, who giveth us richly all things to enjoy; that they do good, that they be rich in good works, ready to distribute, willing to communicate; laying up in store for themselves a good foundation against the time to come, that they may lay hold on eternal life.” 1 Timothy 6:17-19 . MH 213.2"
"Charge them that are rich in this world, that they be not highminded, nor trust in uncertain riches, but in the living God, who giveth us richly all things to enjoy; That they do good, that they be rich in good works, ready to distribute, willing to communicate; Laying up in store for themselves a good foundation against the time to come, that they may lay hold on eternal life."
Ellen White directly references 1 Timothy 6:17-19 in this passage.
"culture, the graces of oratory, are thought to be essential. This is an error. The way of worldly policy is not God's way of reaching the higher classes. That which will reach them effectually is a consistent, unselfish presentation of the gospel of Christ. MH 213.5"
"And my speech and my preaching was not with enticing words of man’s wisdom, but in demonstration of the Spirit and of power:"
Both passages contrast worldly wisdom/oratory with the power of the Spirit in preaching the gospel. EGW's statement amplifies the principle found in 1 Corinthians 2:4.
