Under Gods Command
Romans 10:5-7 Moses describes in this way the righteousness that is by the law: “The man who does these things will live by them.” But the righteousness that is by faith says: Do not say in your heart ‘Who will ascent into heaven? “(that is , to bring Christ down) “or ‘Who will descend into the deep? “(that is, to bring Christ up from the dead).
In order to be saved by the law, a person would have to live a perfect life, not sinning once. Then why did God give the law since he knew people couldn’t keep it? According to Paul one reason the law was given was to show people how guilty they are (Galatians 3:19). The law was a shadow of Christ-that is, the sacrificial system educated the people so that when the true sacrifice came, they would be able to understand his work (Hebrews 10:1-4). The system of ceremonial laws was to last until the coming of Christ. The law points to our need for a Savior.
Paul adapts Moses’ farewell challenge from Deuteronomy 30:11-14 to apply to Christ. Christ has provided our salvation through his incarnation (coming to earth) and resurrection (coming back from the dead). God’s salvation is right in front of us.
Lets Bring it home: He will come to us wherever we are. All we need to do is to respond and accept his gift of salvation. The deep as used here refers to the grave of hades, the place of the dead.
