"...the one who gives us security with you in ChristHave you ever wondered why God doesn't just reveal Himself - make this easy for us? We're on the installment plan!
and who anointed us is God;
he has also put his seal upon us
and given the Spirit in our hearts as a first installment."
Elsewhere in the Gospels (John 14:2-3), we read about the room waiting for us in God's house. God has already covered the security and the first month. Now we have to move in. Every time we stumble, every time we've messed the place up and risk losing that deposit, God steps in. He's willing to forgive us, and He's able.
In the Gospel (Mk 2:1-12), Jesus gives the scribes a powerful demonstration of just what God can do. Forgiving sin is easy for God. All we have to do is ask.
