It is true that some who buy the books will lay them on the shelf or place them on the parlor table and seldom look at them. Still God has a care for His truth, and the time will come when these books will be sought for and read. Sickness or misfortune may enter the home, and through the truth contained in the books God sends to troubled hearts peace and hope and rest. His love is revealed to them, and they understand the preciousness of the forgiveness of their sins. Thus the Lord co-operates with His self-denying workers. 6T 313.3 There are many, who, because of prejudice, will never know the truth unless it is brought to their homes. The canvasser may find these souls and minister to them. There is a line of work in house-to-house labor which he can accomplish more successfully than others. He can become acquainted with the people and understand their true necessities; he can pray with them and can point them to the Lamb of God that taketh away the sin of the world. Thus the way wil…
"For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart."
The EGW passage describes how books containing truth can impact people's lives and bring them to God, which aligns with the idea in Hebrews 4:12 that the word of God is powerful and can discern the thoughts and intents of the heart.
"Let the canvasser remember that he has an opportunity to sow beside all waters. Let him remember, as he sells the books which give a knowledge of the truth, that he is doing the work of God and that every talent is to be used to the glory of His name. God will be with everyone who seeks to understand the truth that he may set it before others in clear lines. God has spoken plainly and clearly. “The Spirit and the bride say, Come. And let him that heareth say, Come.” Revelation 22:17 . We are to make no delay in giving instruction to those who need it, that they may be brought to a knowledge of the truth as it is in Jesus. 6T 314.3"
"And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely."
EGW directly quotes Revelation 22:17 and applies it to the work of canvassers, urging them to share the message of truth.
"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven."
While not a direct quote, the idea of letting one's light shine through good works (selling books with truth) to glorify God is a clear parallel to Matthew 5:16.
