The words "Substitute" and "Representative" are closely related. Both words can be used to articulate the Gospel of Jesus Christ.
SUBSTITUTE: To take the place of another.
REPRESENTATIVE: To act on the behalf of another.
Example of a substitute. Jesus was taking our place on the cross. We are the guilty ones that needed to be crucified, but Jesus took our place and atoned for our sins. "He that knew no sin became sin for us" 2 Corinthians 5:21, just like we did it ourselves. We could not atone for our sins because God requires a perfect sacrifice for the sins of humanity. We are sinners. Sinners cannot atone for the sins of other sinners.
Example of a representative. Jesus came into the world as the new Adam to do for us that which we cannot do for ourselves. By his righteous, sinless life, he offered to God the Father a life of perfect obedience according to his holy law. He did this in our name and on our behalf as our representative. Jesus is our intercessor and our mediator. He is mediating his righteousness on our behalf, Hebrews 7:25. Jesus stands before God's holy court in our name and on our behalf presenting his righteousness on our account, Romans 3:26.
What is the results of the substitutionary and representative work of Christ? All that Jesus did was for our justification. Because of the doing and the dying of Jesus, we can now stand before God in the judgment as justified. Perfect and complete "In Christ" Colossians 2:10.
