Not sure if this is all doctrinally sound, but I sure was proud of myself when I wrote it:

You smiled and betrayed with a kiss and a word.

I in anger drew my sword

And drew the rebuke of our loving Lord.

You did once, but I did thrice

Abandon and betray our Christ.

You hanged yourself on a tree

While I wept softly, bitterly.

And that is where the differences lie

That separate you and I.

While you fell down, your lifeblood spent,

And moldered in a field of blood,

I learned to change, turn, repent,

And give my hands and heart to God.
