"So Jesus said to them again, 'Truly, truly, I say to you, I am the door of the sheep. All who came before Me are thieves and robbers, but the sheep did not hear them. I am the door; if anyone enters through me, he will be saved, and will go in and out and find pasture. The thief comes only to steal and kill and destroy; I came that they may have life, and have it abundantly. I am he Good Shepherd; the Good Shepherd lays down His life for the sheep. he who is a hired hand, and not a shepherd, who is not the owner of the sheep, sees the wolf coming, and leaves the sheep and flees, and the wolf snatches them and scatters them. He flees because his is a hired hand and is not concerned about the sheep. I am the good Shepherd, and I know My own and My own know Me, even as the Father knows Me and I know the Father; and I lay down My life for the sheep," John 10:7-15 (NAS), cf. John 1:1-9, 16- 18.

"Whoever commits sin also commits lawlessness, and sin is lawlessness. and you know that he was manifested to take away our sins, and in Him there is no sin. Whoever abides in Him does not sin. Whoever sins has neither seen him nor known Him. Little children, let no one deceive you. He who practices righteousness is righteous, just as He is righteous. he who sins is of the devil, for the devil has sinned from the beginning. For this purpose the Son of God was manifested, that He might destroy the works of the devil. Whoever has been born of God does not sin, for His seed remains in him; and he cannot sin, because he has been born of God," 1 John 2:4-9 (NKJV).
