36:33-34 Future cleansing from sin and restoration of the Jews to the land and restoration of the land to fruitfulness would all occur at the same time. This shows that the Jews' present occupation of the Promised Land does not fulfill these promises; they have not yet experienced God's cleansing for their sins, which comes with regeneration (cf. Rom. 11).
36:35-36 People would marvel at the lushness of the formerly desolate land and at the strength of the formerly ruined cities of Israel (cf. Isa. 11:6-9; 51:3; Joel 3:18; Amos 9:13-15; Rom. 8:19-22; 2 Pet. 3:13; Rev. 21:1-4, 23-27). The other nations of the world would recognize that Israel's God was responsible for this transformation.
36:37-38 The Lord also promised to respond to the prayers of the Israelites to increase their population. The Jews would fill the cities like the sheep used to fill Jerusalem during the feasts when the people offered large numbers of them as sacrifices to the Lord. These would not be sheep for slaughter but living sacrifices in God's service. This increase in the population in the Promised Land would also convince people of Yahweh's unique deity.
"In analyzing Ezekiel's doctrine of the salvation of Israel, the salient factors are as follows: (1) The preeminent motive in their redemption is the glory of God (vv. 22, 32). (2) Israel will know ultimately that their God is the Lord (v. 38). (3) There will be an abhorrence of their sins (vv. 31-32). (4) Forgiveness of their sins will be realized (v. 25). (5) Regeneration will be effected (11:19; 18:31; 36:26-27). (6) The gift of the Holy Spirit will be granted (v. 27; 37:14). No prophet before him assigns the ministry of the Holy Spirit in regeneration such a precise place as Ezekiel does. (7) Included is obedience to God's laws (v. 27; 11:20)."470
By faith in Jesus Christ, Gentiles as well as Jews presently experience many of the same blessings that God promised here to bring to the entire nation of Israel in the future. But this should not lead us to conclude that these promises have no future fulfillment with Israel but are only fulfilled spiritually in the church.471
"It should be clear that the realization of these promises did not come to fruition in the postexilic period, nor have they been fulfilled today. Israel as a nation is not regathered and has not experienced spiritual regeneration, and the land of Palestine is not characterized by the supernatural fecundity described in Ezekiel 36:22-38."472
