Knowing that our Lord Jesus Christ is both human and divine is vital to the gospel. It is a truth that you and I must believe. If we fail to understand that Jesus is Lord because He is God- if we fail to understand that was able to keep the whole law on our behalf because He is God in the flesh- if we fail to understand that our Lord was able to live a sinless life in order to meet God the Father's requirement for the only acceptable sacrifice for our sin, and He was able to do so because He is God, then you cannot understand the gospel of salvation. It is because Jesus is both fully human and fully God that you and I can call upon Him for the forgiveness of our sins and for the gift of eternal life.
