Last very of Chapter 5, I already quoted it. God is REturning to his place (The Ascension) he will return when they seek his face.
This is where you missed the boat (and the train, plane, automobile and horse, too).
Hosea isn't talking about the ascension of Christ! He is talking about judgment: the judgment of Israel (northern kingdom) that would befall them at the hands of the Assyrians and the judgment of Judah (southern kingdom) at the hands of Babylon!
3 I know Ephraim, and Israel is not hidden from me; for now, O Ephraim, you have played the whore; Israel is defiled.
4 Their deeds do not permit them to return to their God. For the spirit of whoredom is within them, and they know not the Lord.
5 The pride of Israel testifies to his face; Israel and Ephraim shall stumble in his guilt; Judah also shall stumble with them.
6 With their flocks and herds they shall go to seek the Lord, but they will not find him; he has withdrawn from them. (This is before the ascension!)
7 They have dealt faithlessly with the Lord; for they have borne alien children. Now the new moon shall devour them with their fields.
8 Blow the horn in Gibeah, the trumpet in Ramah. Sound the alarm at Beth-aven; we follow you, O Benjamin!
9 Ephraim shall become a desolation in the day of punishment; among the tribes of Israel I make known what is sure.
10 The princes of Judah have become like those who move the landmark; upon them I will pour out my wrath like water.
11 Ephraim is oppressed, crushed in judgment, because he was determined to go after filth.
12 But I am like a moth to Ephraim, and like dry rot to the house of Judah.
13 When Ephraim saw his sickness, and Judah his wound, then Ephraim went to Assyria, and sent to the great king. But he is not able to cure you or heal your wound.
14 For I will be like a lion to Ephraim, and like a young lion to the house of Judah. I, even I, will tear and go away; I will carry off, and no one shall rescue.
15 I will return again to my place, until they acknowledge their guilt and seek my face, and in their distress earnestly seek me.
Hosea 5:3-15 (ESV)
This is the same judgment of which Ezekiel prophesied! And what does He write???
18 Then the glory of the Lord went out from the threshold of the house, and stood over the cherubim.
19 And the cherubim lifted up their wings and mounted up from the earth before my eyes as they went out, with the wheels beside them. And they stood at the entrance of the east gate of the house of the Lord, and the glory of the God of Israel was over them. Ezek 10:18-19 (ESV)
The Temple was God's dwelling place on earth. When God judged Israel and Judah, Ezekiel prophesied that God's glory departed from the Temple: God returned to His heavenly abode!
God's glory returned to the Temple for Daniel's "70 weeks" so that His plan of redemption could come to pass, but when it was time for God to return to earth, He provided His own Temple: the body of His only begotten Son. All Old Testament prophecy dealing with God's return to the people either deals with His return to the rebuilt Temple under Ezra, Nehemiah, and Zerubabbel, or His advent in the form and person of Jesus Christ.
There is only one prophecy that I know of in the Old Testament that deals with Christ's ascension to the Father, and that's in Daniel 7:13-14:
“I saw in the night visions, and behold,
with the clouds of heaven there came one like a son of man,
and he came to the Ancient of Days and was presented before him.
(Notice He is presented before God after ascending! He receives His kingdom in heaven: not on earth!)
14 And to him was given dominion and glory and a kingdom, that all peoples, nations, and languages should serve him; his dominion is an everlasting dominion, which shall not pass away, and his kingdom one that shall not be destroyed. Dan 7:13-14 (ESV)
Christ received the kingdom from His father when He ascended to the father, not when He supposedly returns to earth again!
