Matthew 26:21-22
Now as they were eating, He said, “Assuredly, I say to you, one of you will betray Me.”
And they were exceedingly sorrowful, and each of them began to say to Him, “Lord, is it I?”

Several times through His ministry, Jesus talked about going to Jerusalem and a betrayal.
Now He tells them the betrayer is one of them.
I don’t know if it was guilt, curiosity, fear, or if each actually pondered the thought, but each asked, “Lord, is it I?”
Most of them did betray Christ, just not in the manner of Judas.
Peter denied Jesus three times. That seems like a type of betrayal to me.
No other disciple stood by Jesus at the crucifixion. Only John was there.
That, too, seems like a type of betrayal.

“LORD, IS IT I?”

Think about this, when someone does something that is antichrist, antichurch, or antichristian, that person betrays Christ too.
When someone declares Jesus as Savior but cuss someone out, they betray Christ.
When someone declares Him as Savior but never goes to church, they betray Christ.
Not praying, not reading His word, not sharing His love is all a betrayal.
The good news is forgiveness is available for betrayal. Peter and the rest got it. Judas could have but killed himself.
God does not want to condemn but forgive!
