On Passover, God's people would kill a lamb, spread his blood all over the doorposts and ate the lamb. It was a reminder of the grace of God and a type of things to come. On Yom Kippur, and animal was slaughtered and the animal's blood sprinkled on the people. Again, it is a reminder of the grace of God and a type of things to come. In both cases, the grace of God is declared by reminding his people about the good things God was doing by physicals acts. Lamb was eaten. Blood was sprinkled. Sins were forgive. Acts were remembered. Our God is an unchanging God. If he used physical acts with Israel to remind them what he did and forgive their sins, why would an unchanging God suddenly use "decisions" and "spiritual acts" to declare his love. It doesn't make sense. God used means to deliver forgiveness to his people in the past, so when did God become a Gnostic? Apparently, when he became an American Protestant.
