All we like sheep have gone astray;  we have turned—every one—to his own way;
(Isaiah 53:6a -- ESV)


"What do you think?  If a man has a hundred sheep, and one of them has gone astray, does he not leave the ninety-nine on the mountains and go in search of the one that went astray? ¹³ And if he finds it, truly, I say to you, he rejoices over it more than over the ninety-nine that never went astray.  And if he finds it, truly, I say to you, he rejoices over it more than over the ninety-nine that never went astray. ¹⁴ So it is not the will of my Father who is in heaven that one of these little ones should perish."
(Matthew 18:11-14 -- ESV)
