"God has committed to our hands a most sacred work, and we need to meet together to receive instruction, that we may be fitted to perform this work. We need to understand what part we shall individually be called upon to act in building up the cause of God in the earth, in vindicating God's holy law, and in lifting up the Saviour as the Lamb of God, which taketh away the sin of the world.” John 1:29 . We need to meet together and receive the divine touch, that we may understand our work in the home. Parents need to understand how they may send forth from the sanctuary of the home their sons and daughters so trained and educated that they will be fitted to shine as lights in the world. We need to understand in regard to the division of labor and how each part of the work is to be carried forward. Each one should understand the part he is to act, that there may be harmony of plan and of labor in the combined work of all. 6T 32.3"
"The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world."
EGW directly quotes John 1:29, "Behold the Lamb of God, which taketh away the sin of the world," and uses it in the context of lifting up the Saviour.
"Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen."
EGW's emphasis on instruction, individual roles, and building up God's cause aligns with the Great Commission in Matthew 28:19-20, although it's not a direct quote or explicit allusion.
