The second verse of the moving old hymn "Arise, My Soul, Arise" speaks of Christ's intercessory work on our behalf and the basis on which His prayers are accepted.
He ever lives above; For me to intercede,
His all-redeeming love, His precious blood to plead.
His blood atoned for all our race (repeat)
And sprinkles now the throne of grace.
Our text contains the primary thought Christ is our intercessor, pleading with the Father to save us from our sins, for which the penalty has been paid by His "sacrifice . . . for this he did once, when he offered up himself" (Hebrews 7:27). It is "the precious blood of Christ, as of a lamb without blemish and without spot" (1 Peter 1:19) which pleads for our forgiveness. He does this for us because He "loved us, and washed us from our sins in his own blood" (Revelation 1:5) as we come to God in repentant faith.
Because Jesus was Himself a fully righteous man, He could die on another's behalf; because He was fully God the Son, His death was sufficient to pay the penalty for the whole human race: "Jesus Christ the righteous; And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world" (1 John 2:1-2). "Thou art worthy . . . for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation" (Revelation 5:9).
Only in this way can we come "to the general assembly and the church of the firstborn, which are written in heaven, and to God, the Judge of all, and to the spirits of just men made perfect, And to Jesus the mediator of the new covenant, and to the blood of sprinkling" (Hebrews 12:23-24). JDM
