"While the great final reward is given at Christ's coming, true-hearted service for God brings a reward, even in this life. Obstacles, opposition, and bitter, heart-breaking discouragements, the worker will have to meet. He may not see the fruit of his toil. But in face of all this he finds in his labor a blessed recompense. All who surrender themselves to God in unselfish service for humanity are in co-operation with the Lord of glory. This thought sweetens all toil, it braces the will, it nerves the spirit for whatever may befall. Working with unselfish heart, ennobled by being partakers of Christ's sufferings, sharing His sympathies, they help to swell the tide of His joy, and bring honor and praise to His exalted name. In fellowship with God, with Christ, and with holy angels, they are surrounded with a heavenly atmosphere, an atmosphere that brings health to the body, vigor to the intellect, and joy to the soul. GW 513.1"
"Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls."
Both passages discuss finding rest/recompense in service to God, even amidst difficulties. Matthew 11:29 speaks of finding rest for the soul through meekness and learning from Christ, while the EGW passage speaks of finding reward and strength in unselfish service and fellowship with God.
"For it is God which worketh in you both to will and to do of his good pleasure."
Both passages highlight God's active role in enabling believers to do good. Philippians 2:13 states that God works in believers to will and to do His good pleasure, while the EGW passage describes how surrendering to God in unselfish service leads to cooperation with God and a strengthening of the will and spirit.
"All who consecrate body, soul, and spirit to God's service will be constantly receiving a new endowment of physical, mental, and spiritual power. The inexhaustible supplies of heaven are at their command. Christ gives them the breath of His own spirit, the life of His own life. The Holy Spirit puts forth His highest energies to work in heart and mind. GW 513.2"
"That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;"
Both passages speak of being strengthened by the Spirit of God. EGW expands on the idea of receiving power from God for service, while Ephesians 3:16 focuses on inner strengthening. The connection is thematic and meaningful.
"He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water."
Both passages relate to receiving something from Christ that brings life and power. John 7:38 speaks of 'rivers of living water' flowing from believers, while EGW speaks of Christ giving 'the breath of His own spirit, the life of His own life.' The connection is thematic, though not a direct quote or explicit allusion.
"drought, and make fat thy bones: and thou shalt be like a watered garden, and like a spring of water, whose waters fail not.” [ Isaiah 58:8-11 .] GW 513.3"
"Then shall thy light break forth as the morning, and thine health shall spring forth speedily: and thy righteousness shall go before thee; the glory of the Lord shall be thy rereward. Then shalt thou call, and the Lord shall answer; thou shalt cry, and he shall say, Here I am. If thou take away from the midst of thee the yoke, the putting forth of the finger, and speaking vanity; And if thou draw out thy soul to the hungry, and satisfy the afflicted soul; then shall thy light rise in obscurity, and thy darkness be as the noonday: And the Lord shall guide thee continually, and satisfy thy soul in drought, and make fat thy bones: and thou shalt be like a watered garden, and like a spring of water, whose waters fail not."
Ellen White directly references Isaiah 58:8-11 in this passage.
