I. Noah was saved by the putting away of sin by death in mortal body.
II. Paul taught us to kill the outward man.
III. Jesus instructed us to practice baptism, not for the cleansing of flesh, but the renewing of the mind.
One can conclude that according to 1 Peter 3:21 Baptism is the essential stepping stone to cross over into Christ.
Before the flood, Noah almost died with the sin. But because of God's Covenant which was offered only to Noah (and his family) because of grace, the flood only killed the sin. We too can take part in the flood. Let it kill the sin, so that we - like Noah - wont be found dead in sin.
I thank God, that I could find grace in His eyes through Christ, My Savior.
