Romans 7:4 says we are 'dead to the law through ... Christ.' What does this mean? The context shows that it refers to the 'old man' that perished at baptism.
Galatians 4:4 says that Jesus was "born under [the] law." Some use this to say that while Christ had to keep all the rituals, we do not have to follow His example.
Christ will empower us, but will not live our lives for us. The marching orders for our pilgrimage derive from God's Word, containing His holy law.
Ephesians 2 says Christians were spiritually dead. Thankfully, God resurrected us from the grave through the substitutionary sacrifice of Christ.
'Grace' is a term that represents God's awesome generosity toward us, His continuously flowing blessings and saving acts. It goes beyond just forgiveness.
When we mortify the flesh, refusing to feed the hungry beast of our carnal nature, we suffer. Suffering for righteousness' sake helps us to know Christ.
Christ's sacrifice was not merely substitutionary, but representative, with Christ giving us a pattern for life - mortifying our flesh and putting out sin.
