John 1:50

Jesus said, “You believe because I told you I saw you under the fig-tree. You shall see greater things than that.”

Note that as immature as the faith of Nathanael was, Jesus accepted it. We don’t need to be spiritual giants to get saved.

It was probably not a revelation from Jesus of seeing you under a fig tree that triggered your faith, causing you to finally place your trust in Him, but the additional promise that Jesus made to Nathanael was valid for you when you also believed. Has Jesus fulfilled this promise to you? How?
