Jesus had a definite plan.  Jesus and God were in control of that last Passover meal with the disciples.  Even the location was kept secret.

Judas was the betrayer.

However, all the disciples understood that they had the potential to betray Jesus.  Thus they asked, "Is It I, Lord?"

We all must ask that difficult question.  It could be and probably has been all of us.

But the good news is that the story doesn't end here.  Jesus was in control, thus it means Jesus willing gave his live for us.  His body was broken; his blood was shed for us.
