"But the law is not the end of it. It is, rather, to prepare us for something else. We need the law, we need it to break us, to smash our pride, to show us how helpless we are, so that we can be ready to receive the message of The Gospel."Rigor
What is this message? That Christ, the Son of God, born of a virgin, lived the sinless life that we cannot live. Jesus the Christ, the Messiah, was crucified for our sins, the sacrifice for our atonement and redemption, as this passage said. He rose from the dead, and ascended to the right hand of the Father. And now we, through repentance for our sins and faith in Christ, may be made clean of our sins and receive eternal life."
Behold this man! Behold, the Lamb of God, who takes away the sins of the world! As it it written, God has shown us his love for us, in that while we were still sinners, Christ died for us, so that we can have this righteousness spoken of in this passage.
