"heart will always reveal its presence by diffusing itself. Philip went in search of Nathanael, and as he called, Nathanael answered from his place of prayer under the fig tree. Nathanael had not had the privilege of listening to the words of Jesus, but he was being drawn toward Him in spirit. He longed for light, and was at that moment sincerely praying for it. Philip with joy exclaimed: “We have found Him, of whom Moses in the law, and the prophets, did write, Jesus of Nazareth.” John 1:45 . At Philip's invitation Nathanael sought and found the Saviour, and in his turn joined in the work of winning souls for Christ. 6T 428.2"
"Philip findeth Nathanael, and saith unto him, We have found him, of whom Moses in the law, and the prophets, did write, Jesus of Nazareth, the son of Joseph."
Ellen White directly references John 1:45 in this passage.
