"One part of the ministry of heavenly angels is to visit our world and oversee the work of the Lord in the hands of His stewards. In every time of necessity they minister to those who as co-workers with God are striving to carry forward His work in the earth. These heavenly intelligences are represented as desiring to look into the plan of redemption, and they rejoice whenever any part of God's work prospers. 6T 456.1"
"Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?"
The EGW passage directly echoes the principle in Hebrews 1:14 regarding the ministry of angels to those who will inherit salvation.
"Angels are interested in the spiritual welfare of all who are seeking to restore God's moral image in man; and the earthly family are to connect with the heavenly family in binding up the wounds and bruises that sin has made. Angelic agencies, though invisible, are co-operating with visible human agencies, forming a relief association with men. The very angels who, when Satan was seeking the supremacy, fought the battle in the heavenly courts and triumphed on the side of God, the very angels who shouted for joy over the creation of our world and its sinless inhabitants, the angels who witnessed the fall of man and his expulsion from his Eden home..these very heavenly messengers are most intensely interested to work in union with the fallen, redeemed race for the salvation of human beings perishing in their sins. 6T 456.2"
"Likewise, I say unto you, there is joy in the presence of the angels of God over one sinner that repenteth."
Both passages highlight the joy of angels in the salvation of sinners. The EGW passage expands on this theme, connecting it to the broader context of angelic involvement in human redemption.
"To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,"
Both passages touch on the idea of heavenly beings (angels, principalities, powers) being aware of and involved in God's work on earth, particularly related to the church and salvation. The connection is not explicit, but the thematic overlap is present.
