John speaks a lot about Jesus. See Who is the Son of the Almighty?
To see highlights for the following scriptures in John, see “Who can be rightfully called God?”
Some wonder why Mary was told to not cling to Christ yet he told Thomas to touch him. It’s rather simple. Mary was overjoyed to see Yeshua (Jesus) alive! She was clinging to him because of being overjoyed! Yeshua gave her an assignment to tell the others. He had not ascended yet and she had work to do, in the meantime! When Thomas saw Yeshua, he doubted and Yeshua told him to touch him to erase all doubts. Pretty simple.
