"As the lesson of the preparatory service is thus learned, the desire is kindled for a higher spiritual life. To this desire the divine Witness will respond. The soul will be uplifted. We can partake of the Communion with a consciousness of sins forgiven. The sunshine of Christ's righteousness will fill the chambers of the mind and the soul temple. We “behold the Lamb of God, which taketh away the sin of the world.” John 1:29 . DA 651.1"
"The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world."
Ellen White directly references John 1:29 in this passage.
"heaven's treasure. His disciples, in performing the same rite, pledge themselves in like manner to serve their brethren. Whenever this ordinance is rightly celebrated, the children of God are brought into a holy relationship, to help and bless each other. They covenant that the life shall be given to unselfish ministry. And this, not only for one another. Their field of labor is as wide as their Master's was. The world is full of those who need our ministry. The poor, the helpless, the ignorant, are on every hand. Those who have communed with Christ in the upper chamber will go forth to minister as He did. DA 651.2"
"If I then, your Lord and Master, have washed your feet; ye also ought to wash one another’s feet."
The EGW passage directly references and expands upon the act of foot washing described in John 13:14, connecting it to service and ministry.
"Jesus, the served of all, came to be the servant of all. And because He ministered to all, He will again be served and honored by all. And those who would partake of His divine attributes, and share with Him the joy of seeing souls redeemed, must follow His example of unselfish ministry. DA 651.3"
"Even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many."
Both passages emphasize Jesus's ministry and service to others, highlighting the idea that true greatness comes from serving rather than being served.
"All this was comprehended in the words of Jesus, “I have given you an example, that ye should do as I have done to you.” This was the intent of the service He established. And He says, “If ye know these things,” if you know the purpose of His lessons, “happy are ye if ye do them.” DA 651.4"
"If ye know these things, happy are ye if ye do them."
The EGW passage directly quotes John 13:17 and connects it to the example Jesus set through the foot washing service.
