Dr. James White said in his teaching on Hebrews: "The only true path to exaltation and being commended by God is that of humiliation. The person who seeks exaltation will be humbled. The person who is humbled will be exalted by God."
Instead of exalting Christ in our life and humbling ourselves, we so often exalt ourselves and bring Christ down from where He rightfully belongs and that is Lord and God of all. Instead of exalting Christ, we exalt idols after our own imaginations and fleshly desires and we worship them which means that we are ultimately worshiping ourselves instead of God.
I am the good shepherd; the good shepherd lays down His life for the sheep. (John 10:11 NASB)
Many years ago, one of England's leading actors was asked to recite for the pleasure of his fellow guests. He consented and asked if there was anything special that his audience would like to hear.
After a moment's pause, an old Pastor present said: "Could you, sir, recite to us the Twenty-third Psalm?"
A strange look passed over the actor's face; he paused for a moment, and then said: "I can, and I will, upon one condition; and that is that after I have recited it, you, my friend, will do the same."
John MacArthur in his commentary on the book of Hebrews states the following: "Keep in mind that the book of Hebrews is written to Jewish people, primarily to Jewish believers but also to Jewish unbelievers. Both groups are pressed with the truth that the New Covenant is better than the Old – that Jesus Christ is the better Priest, and the better Mediator, and that He is the final Priest and the final Sacrifice at the same time (MacArthur, 1983. p.22)
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 their comes only to steal and kill and destroy; I came that they may have life, and have it abundantly.
John MacArthur in his commentary on John 10 says, "Each village in the sheepherding regions of Palestine had a fold where sheep were kept at night. The shepherds would graze their flocks in the surrounding countryside during the day and then lead them back to the communal sheepfold in the evening. There the shepherds would stop each sheep at the entrance with their rods and carefully inspect it before allowing it to enter the fold. Once in the fold, the sheep were in the care of during the night. He would give only the shepherds access to the sheepfold; therefore, anyone who could not enter by the door into the fold of the sheep, but climbed up some other way, was a thief and a robber (MacArthur, 2006. p.425).
