God seals His people and that does two things. 1) it enables them to stand at the interface between heaven and earth...not to stumble but to stand, because the Christian is that interface; and 2) this sealing activates their faith to function. The Holy Spirit's presence in them assists and activates their faith, so that they can be faithful even in difficult circumstances.
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]
