"As the knowledge of the truth is received, let it be imparted to those who are in darkness, without God and without hope in the world. In such labor there is a variety of minds to deal with, and God will greatly bless His servants as they look to Him for wisdom. The Holy Spirit will come to all who are begging for the bread of life to give to their neighbors. 6T 90.1"
"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
Both passages emphasize sharing one's faith and good works to glorify God and bring light to others.
"Instead of holding institutes to fit ministers for their work, let these ministers be given work to do in places where camp meetings have been held. After being fed with the bread of life by a miracle of God's mercy, let them work to feed others. 6T 90.2"
"Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give."
Both passages emphasize the principle of freely sharing what one has received, whether it be healing or spiritual nourishment.
"And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst."
EGW uses the 'bread of life' metaphor from John to encourage ministers to share the spiritual nourishment they have received.
"There are in the ministry men of faith and prayer, men who can say: “That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; ... that which we have seen and heard declare we unto you.” 1 John 1:1-3 . These men are to instruct others. Let workers be trained by actual labor in connection with experienced men. 6T 90.4"
"That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;"
EGW directly quotes 1 John 1:1, making it an explicit allusion.
"That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; (For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;) That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ."
Ellen White directly references 1 John 1:1-3 in this passage.
"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."
EGW directly quotes 1 John 1:1-3. While 2 Timothy 2:2 is about training others, the primary connection is the direct quote from 1 John.
