Ephesians 4: 24
. . . and put on the new self, which in the likeness of God has been created in righteousness and holiness of the truth.
You have been created a new creature. You have been created in righteousness and truth. Jesus said in John 14: 6 “I am the way, and the truth, and the life.” You have been created in the truth because Jesus is the truth and you are the righteousness of God because Jesus gave you right standing with God through his blood. That is what righteousness means, “right standing with God.”
In this passage Paul is trying to lead the church at Ephesus to put away their old man and old ways and to realize that they have been made new by the shed blood of Jesus Christ. He is showing them that their new selves have been forged in truth and righteousness not because of anything they did but by what Jesus did. He wants them to receive the gift of holiness and walk therein.
Jesus paid an enormous price so that we might become the righteousness of God in Him. We have our part to play though. We must receive this gift and walk in it. It is not by works that we are saved or righteous, it is only by the price paid by Jesus. Now in humble gratitude we proclaim that we are new and glorious creatures because our Lord has made us so. It is not by our works but only by our faith in His sacrifice. Don’t make his sacrifice of nil effect though. As Paul says, “put on the new self.”
