When we consider of the admonition to be men, we must think of Jesus Christ. The Lord asked His disciples what manner of men they should be, and then answered, "Verily I say unto you, even as I Am." Jesus told his Apostles, "Whosoever of you will be the chiefest shall be the servant of all."
He gave His life to redeem mankind. Surely we can accept responsibility for those He entrusts to our care. Let us be men, even as He is.
