"The Lord Jesus will work miracles for His people. In the sixteenth of Mark we read: “So then after the Lord had spoken unto them, He was received up into heaven, and sat on the right hand of God. And they went forth, and preached everywhere, the Lord working with them , and confirming the word with signs following.” Verses 19, 20 . Here we are assured that the Lord was qualifying His chosen servants to take up medical missionary work after His ascension. 7T 114.2"
"And they went forth, and preached every where, the Lord working with them, and confirming the word with signs following. Amen."
The EGW passage directly quotes Mark 16:19-20 and explicitly connects it to the idea of the Lord working with His servants in medical missionary work. This is a clear and undeniable explicit allusion.
