Jesus told Nathaniel that he knew about him supernaturally, but that he would do things that were more surprising than that.

John 1:43-51

43 The next day Jesus decided to leave the Jordan River valley. He went to Galilee district and (OR, on the way there he) found a man named Philip. Jesus said to him, “Come with me!” 44 Philip and Andrew and Peter were all from Bethsaida town. 45 Then Philip searched for Nathaniel and found him, and said to him, “We have met the Messiah, the one Moses wrote about! The prophets also prophesied that he would come. He is Jesus, from Nazareth town. His father’s name is Joseph.” 46 Nathaniel replied, “Nazareth? ◄Nothing good can come from such an unimportant place!/Can anything good come from such an unimportant place?► [RHQ]” Philip replied, “Come and see!” 47 When Jesus saw Nathaniel approaching, he said about Nathaniel, “Here is an example of a good Israelite! He never deceives anyone!” 48 Nathaniel asked him, “How do you know what I am like?” Jesus replied, “I saw you before Philip called you, when you were by yourself under the fig tree.” 49 Then Nathaniel declared, “Teacher, you must be ◄the Son of God/the person who is both God and man►! You are the King of Israel we have been waiting for!” 50 Jesus replied to him, “You [RHQ] believe those things about me because I told you I saw you when you were under the fig tree. I was able to see you supernaturally even though I was far away from you. But you will see me do things that are more surprising than that!” 51 Then Jesus said to him, “This is the absolute truth: Just like what your ancestor Jacob saw long ago in a vision, some day you (pl) will see heaven opened up, and you will see God’s angels ascending from me and descending on me, the one who came from heaven.”
