The Son of Man betrayed by a kiss.
A sweet kiss of friendship.
Just a kiss.
Many years ago when I lived in Boston and was very near to falling, a Jewish kid cautioned me, "Do not sell your birthright for a meal." (As did Esau.) At the time, someone attracted to me, had been suggesting we move in together.
It is very easy to betray Christ, through some inordinate affection, or disordered attraction. Just one kiss...
One little compromise for a 'greater good' - or one's 'happiness'.
It's just a kiss away, kiss away, kiss away...
