Without Christ, aliens, strangers, having no hope, and without God. This was us before God. The attached picture is from the photo collection in SwordSearcher, one of my Bible study software programs. This notice was hung on the temple in Jerusalem, forbidding strangers to enter into the temple. The cross changed all that for Christians. We have access to God directly in prayer, as well as in church. As they say, the ground is level at the foot of the cross. Galations 3:28. But, the picture gives you a sense of our alienation from God.
Amazingly, we were aadopted by blood!
