In John 13:18-30, Jesus announces in the upper room that on of the disciples will betray him. Jesus is fully aware of the spiritual condition of Judas. Judas did not lose his salvation – he never possessed grace (John 13:10). Jesus extends the morsel of food to Judas in a final gesture of love and opportunity of grace, but Judas rejects Christ and heads out of the room, into the darkness forever. It is possible to know a lot about Jesus and still be outside of His grace. Jesus is the Light of the World, come to Him in faith today.
