Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:) Or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.) – Romans 10:6,7

A voice cries “Who shall ascend into heaven?” The gospel replies, if you did ascend to heaven what would you do there, without Christ, the anointed Savior? You say, “Who shall descend into the deep?” Listen, man. If you were to descend there, what would you do without Him whom God has anointed to save? If you find Him it will not much matter where you find Him, in heaven or in the deep, for He must be almighty everywhere. Now hearken. Thou sayest, “Who shall ascend into heaven?” the top and bottom of such an ascent must be, “to bring Christ down.” Hear this! Jesus has come down: years ago He left the glories of His Father…Oh, my hearer, our salvation lies in this! Not in our descending, but in Christ’s descending our hope is to be found. Listen to it, lost ones; you need not climb to heaven: Christ has come down from heaven to you; and if you lie among the spiritually dead to-day, or think you do, He has come down to you, and you need not enquire how you can go up to Him. No prayers, or tears, are wanted to bring Him down: He has already come and is near at hand… You need not “bring up Christ again from the dead,” for the Lord has risen indeed…He has gone up to the Father’s throne, as the sinner’s Savior: at the throne He stands to-day to intercede for sinners, and from that throne He bends to comfort those who come to Him. Now, your hope lies wholly in what this Son of God did in His descent and ascent. God has brought Him again from the dead and exalted Him at His own right hand, and this is not for Himself, but for all those who trust in Him. His death is instead of the death of our souls: His life is the life of our spirits. Now, soul, thou hast nothing to do with asking vain questions; thou hast to accept the result of the Savior’s actual performances. The saving work is done, done by Him who was anointed of the Lord to do it. ~ C.H. Spurgeon
