John 21:1
1After these things, Jesus revealed himself again to the disciples at the sea of Tiberias. He revealed himself this way.
The Gospel is not finished with locked rooms. Jesus reveals himself again—by a lake the disciples know, in a way they can tell. Revelation is personal and public enough to be narrated.
Listen here for a risen Lord who keeps coming near. Grace does not retire after one appearance; it seeks the same men in their ordinary place so they may recognize him and respond.
John still labors, as Calvin says, to prove the resurrection. “Revealed himself” is the verb of divine self-disclosure, not a chance meeting on a beach.
The Sea of Tiberias is an appointed stage. The Father who raised the Son now times a third manifestation to the disciples so that faith in the risen Christ is confirmed, not left to rumor.
