The Lord Jesus Christ is the only begotten Son of God. In the flesh, He took on full humanity while retaining full deity (John 1:14). In fulfillment of Old Testament prophecy, He came first to Israel as her Messiah-King (Matthew 15:24), and being rejected of that nation (John 1:11), He gave Himself as a ransom for all (1 Timothy 2:6), dying bodily upon the cross as a representative, a substitutionary sacrifice for the sins of man (1 Peter 3:18), His death completely and perfectly satisfying the righteousness and justice of God (Romans 3:25-26), thereby providing the basis for reconciling the relationship between sinful man and a holy God, making possible the restoring of the repentant sinner to a new life (2 Corinthians 5:17).
The Lord Jesus Christ arose from the dead in the same body, He ascended into heaven and is now exalted at the right hand of the Father (Hebrews 1:3). The exalted Christ is presently acting as the believer’s High Priest (Hebrews 4:14), whereby He is fulfilling the ministries of Intercessor (Hebrews 7:25) and Advocate (1 John 2:1) as well as the ministry of Mediator between God and man (1 Timothy 2:5). He is also the Head of the Church, the Body of Christ (Colossians 1:18).
