“that they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me.” John 17:21

Our Lord Jesus Christ desires us to have a distinct recognition of the Father’s love to Him. He wants the love wherewith the Father loves Him to be felt in us, so that we may say, “Yes, I know the Father loved Him, for I, who am such a poor, unworthy, and foolish creature, yet love Him; and, oh, how His Father must love Him.” I love Him! Ay, by His grace, it were a blessed thing to die for Him; but if I love Him, oh, how must His Father love Him who can see all His beauty, and can appreciate every distinct piece of loveliness that is in Him! …For, first and foremost, the Father and the Son are one: they are one in essence. The Saviour has been with the Father from the beginning, and His delight has been with Him, even as the Father testified, “This is My beloved Son, in whom I am well pleased.” Oh, do try to feel, if you can, the love of the Father to His Son, or else you will not love the Father as you should for the amazing sacrifice which He made in giving Jesus to us. Think what it cost Him to tear His Well-Beloved from His bosom and send Him down below to be “despised and rejected.” Think what it cost Him to nail Him up to yonder cross, and then forsake Him and hide His face from Him, because He had laid all our sins upon Him. Oh, the love He must have had to us thus to have made His best Beloved to become a curse for us, as it is written, “Cursed is everyone that hangeth on a tree.” I want you to get this right into your souls, dear friends. Do not hold it as a dry doctrine, but let it touch your heart. Let it flow into your heart like a boiling stream, till your whole souls become like Icelandic geysers, which boil and bubble up and send their steam aloft into the clouds. Oh, to have the soul filled with the love of the Father towards Him who is altogether lovely.~ C.H. Spurgeon
