Only one Mediator can lay His hands on both God and man. No other is qualified; no other is an acceptable “go-between.” Jesus is “God with us” (Matthew 1:23). No angel, no pope, no bishop, no saint, no mother, no pastor, no preacher - no one else is a divinely approved and appointed mediator.
Jesus mediates between God and man with the view of reconciliation and salvation. He was both divine and human, making it possible for Him to bridge the gap. In Christ “dwells all the fullness of the Godhead bodily” (Colossians 2:9). He comprehends both God’s claims and demands and man’s needs and petitions. Jesus is holy and righteous, executin justice with mercy. He, also, sympathizes with man’s frailties, temptations, infirmities and suffering (cf. Hebrews 4:15).
God’s immeasurable love moved Him to sacrifice the Christ to be the propitiation for the sins of the whole world (cf. Romans 5:8; I John 2:2). Jesus is the means by which sin is remitted. When a believer obediently applies the blood of God’s Son, the heavenly Father is appeased (cf. Romans 6:3, 4; I Peter 3:21). Without Christ’s mediatorial work, there would be no redemption and no promise of eternal life. “He is the Mediator of the new covenant, by means of death” (Hebrews 9:15).
