All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all. Isaiah 53:6
And he spake this parable unto them, saying, What man of you, having an hundred sheep, if he lose one of them, doth not leave the ninety and nine in the wilderness, and go after that which is lost, until he find it? Luke 15:3,4 And if so be that he find it, verily I say unto you, he rejoiceth more of that sheep, than of the ninety and nine which went not astray. Matthew 18:13 And when he hath found it, he layeth it on his shoulders, rejoicing.I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance. Luke 15:5,7 For the Son of man is come to save that which was lost. Matthew 18:11 -- I have gone astray like a lost sheep; seek thy servant; for I do not forget thy commandments. Psalm 119:176
for ye were as sheep going astray, but ye turned back now to the shepherd and overseer of your souls.1 Peter 2:25
The LORD is my shepherd; I shall not want. He maketh me to lie down in green pastures: he leadeth me beside the still waters.He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake. Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the LORD for ever. Psalm 23:1-4,6 --
I am the good shepherd: the good shepherd giveth his life for the sheep. John 10:11
