The Cross is the Mark of God, the Seal of God

John 3:16 - For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.

Old Testament Precusors of the Cross

The First Passover
 Only the houses with doors whose top and posts are marked with blood are spared. This forms a Tau, a Cross †
 Note that the modern Tau is an open door, top and sides ת

Exodus 12:22 And ye shall take a bunch of hyssop, and dip it in the blood that is in the bason, and strike the lintel and the two side posts with the blood that is in the bason; and none of you shall go out at the door of his house until the morning.

Exodus 12:23 For the LORD will pass through to smite the Egyptians; and when he seeth the blood upon the lintel, and on the two side posts, the LORD will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you.

The Tau, a Cross, is the Mark of God †

The Second Passover
 The Righteous are marked with a Tau, the Cross †
