Another thing to consider is that God did not hold the children of Israel under 20 years of age accountable for the rebellion in the Wilderness (see Numbers 14).
Except for a very few older persons, the rest were condemned to die in the Wilderness for their rebellion.
By type, these were still His REDEEMED.
Blessed is the man to whom the Lord will not reckon sin [Ro 4:8]. Even after all the wickedness Israel had done in the wilderness after leaving Egypt (unbelief, disobedience, murmuring, idolatry, fornication, rebellion, etc.), and even with Balaam wanting so badly to curse Israel, God made Balaam to declare, "
He hath not beheld iniquity in Jacob;
Neither hath he seen perverseness in Israel: Jehovah his God is with him, And the shout of a king is among them" [Nu 23:21].
There was an entire generation of His, redeemed with a mighty hand from
the House of Bondage, who rejected His gospel command to go in and possess
the Promised Land, who became 'children of His wrath', condemned to wander lost in the Wilderness for the rest of their lives. Yet throughout all their wandering/chastening in
the Wilderness He still gave them shade by day and light by night, He fed them manna, gave them water, their clothes never wore out, their feet didn't blister, etc., He was with them always even though He granted them no repentance to enter into His Rest. They wandered in
the Wilderness for the rest of their lives when they could have spent it in
the Land of Milk & Honey, had they only believed
THE GOSPEL that it was their's for the taking.
