God seals them in. The Biblical pattern of chaos-water-salvation is visible here in the first use of the 'ark' (Moses & Covenant are the other two). Chaos is the corruption, Water continues/completes the corruption, God's covenant completes the world change.
So roll up your sleeves, put your mind in gear, be totally ready to receive the gift that’s coming when Jesus arrives. Don’t lazily slip back into those old grooves of evil, doing just what you feel like doing. You didn’t know any better then; you do now. As obedient children, let yourselves be pulled into a way of life shaped by God’s life, a life energetic and blazing with holiness. God said, “I am holy; you be holy. [1 Peter 1:13-16]
