John 11:45
45Therefore many of the Jews who came to Mary and saw what Jesus did believed in him.
Wesley: many believed, and so the Son of God was glorified, as he had said in v. 4. Sight of the sign becomes faith in the person. The therefore is moral, not mechanical: they had come with Mary, they saw, they believed.
Classical Arminians take this believing as a response to sufficient light. The same raising that some will report as a threat, these receive. “Whoever believes” in vv. 25–26 is already gathering names in Bethany.
Calvin: Christ did not let the miracle be without fruit; by it he drew some to faith. Miracles prepare for faith or confirm it; here they produce admiration that submits to be taught. Bare miracle could not have been enough; believe means willingness to embrace his doctrine.
The fruit is Christ’s. Many believing is the glory appointed in v. 4, given through a sign, received as faith the Lord himself yields.
Key contrast Either reading: many believed because of what they saw. Arminians emphasize a free, sincere response to public evidence. Reformed interpreters usually stress that the sign is God’s appointed means by which he actually draws people—miracle plus the Son’s power to give the faith the sign aims at.
