"The duty and delight of all service is to uplift Christ before the people. This is the end of all true labor. Let Christ appear; let self be hidden behind Him. This is self-sacrifice that is of worth.— Testimonies for the Church 9:144-147 . GW 485.3"
"He must increase, but I must decrease."
Both passages emphasize the importance of Christ's prominence over self. John 3:30 expresses this as 'He must increase, but I must decrease,' while EGW frames it as uplifting Christ and hiding self behind Him.
