"The heart of the true minister is filled with an intense longing to save souls. Time and strength are spent, toilsome effort is not shunned; for others must hear the truths that brought to his own soul such gladness and peace and joy. The Spirit of Christ rests upon him. He watches for souls as one that must give an account. With his eyes fixed on the cross of Calvary, beholding the uplifted Saviour, relying on His grace, believing that He will be with him until the end, as his shield, his strength, his efficiency, he works for God. With invitations and pleadings, mingled with the assurances of God's love, he seeks to win souls to Jesus, and in heaven he is numbered among those who are “called, and chosen, and faithful.” Revelation 17:14 . AA 371.1"
"These shall make war with the Lamb, and the Lamb shall overcome them: for he is Lord of lords, and King of kings: and they that are with him are called, and chosen, and faithful."
Ellen White directly references Revelation 17:14 in this passage.
