It's the same today. There's a fiercely loyal minority still—not many, perhaps, but probably more than you think. They're holding on, not because of what they think they're going to get out of it, but because they're convinced of God's grace and purpose in choosing them. If they were only thinking of their own immediate self-interest, they would have left long ago. (romans 11:2-6)
15 Neither do men light a lamp, and put it under the bushel, but on the stand; and it shineth unto all that are in the house.
16 Even so let your light shine before men; that they may see your good works, and glorify your Father who is in heaven. (matt 5:14-16)
