Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew Him not.-1 John 3:1

“Behold, what manner of love the Father hath bestowed on us.” Consider who we were, and who we are now; aye, and what we feel ourselves to be even when divine grace is powerful in us. And yet, beloved, we are called “the sons of God.” It is said that when one of the learned heathens was translating this, he stopped and said, “No; it cannot be; let it be written ‘Subjects,’ not ‘Sons,’ for it is impossible we should be called ‘the sons of God.’ ” What a high relationship is that of a son to his father! What privileges a son has from his father! What liberties a son may take with his father! and oh! what obedience the son owes to his father, and what love the father feels towards the son! But all that, and more than that, we now have through Christ. “Behold!” ye angels! stop, ye seraphs! here is a thing more wonderful than heaven with its walls of jasper. Behold, universe! open thine eyes, O world. “Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God; therefore the world knoweth us not, because it knew Him not.” Well, we are content to go with Him in His humiliation, for we are to be exalted with Him.~ C.H.
