"Then as you meet from Sabbath to Sabbath, sing praises to Him who has called you out of darkness into His marvelous light. “Unto Him that loved us, and washed us from our sins in His own blood” let the heart's adoration be given. Let the love of Christ be the burden of the speaker's utterance. Let it be expressed in simple language in every song of praise. Let the inspiration of the Spirit of God dictate your prayers. As the word of life is spoken, let your heartfelt response testify that you receive the message as from heaven. This is very old- fashioned, I know; but it will be a thank offering to God for the bread of life given to the hungry soul. This response to the inspiration of the Holy Spirit will be a strength to your own soul and an encouragement to others. It will give some evidence that there are in God's building living stones that emit light. 6T 367.1"
"And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood,"
The EGW passage directly quotes Revelation 1:5.
"But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light:"
EGW directly quotes 1 Peter 2:9, making it an explicit allusion.
"Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord;"
Both passages encourage singing praises and spiritual songs. The connection is thematic, not a direct quote, but relevant.
"While we review, not the dark chapters in our experience, but the manifestations of God's great mercy and unfailing love, we shall praise far more than complain. We shall talk of the loving faithfulness of God as the true, tender, compassionate shepherd of His flock, which He has declared that none shall pluck out of His hand. The language of the heart will not be selfish murmuring and repining. Praise, like clear-flowing streams, will come from God's truly believing ones. “Goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Lord forever.” “Thou shalt guide me with Thy counsel, and afterward receive me to glory. Whom have I in heaven but Thee? and there is none upon earth that I desire beside Thee.” Psalm 23:6 ; 73:24, 25 . 6T 367.2"
"Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Lord for ever."
The EGW passage directly quotes Psalm 23:6.
"And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand."
Both passages refer to the security of believers in God's care, specifically that none can 'pluck them out of His hand.' While not a direct quote, the thematic connection is strong.
