No — acknowledging the God of heaven does not equate to salvation.
In Revelation 11:13, the remnant was affrighted and gave glory to the God of heaven, but the text does not say they were saved. Les Feldick points out that these were Jewish people fleeing Jerusalem in unbelief concerning the Messiah, still not recognizing Jesus as the Christ. Fear and religious acknowledgment may get God's attention, but they are not the faith that saves.
Revelation 11:13 — This is the verse where the remnant becomes afraid and gives glory to the God of heaven, the exact passage under question.
Revelation 11:13 records that at the midpoint of the Tribulation, the same hour the two witnesses ascended into heaven, a great earthquake struck Jerusalem. A tenth part of the city fell, and seven thousand people were killed. The remnant that remained was terrified and gave glory to the God of heaven. The passage does not say that they were saved, that they confessed Jesus as the Christ, or that their acknowledgment of God resulted in salvation. It simply records that they were affrighted and gave glory.
Les Feldick teaches that giving glory to the God of heaven can be a purely religious response and is not the same as salvation. He points out that the remnant in Revelation 11:13 were Jews fleeing Jerusalem, and they went out in unbelief concerning the Messiah. They had practiced temple worship for three and a half years and still did not recognize Jesus as the Christ. Les compares them to religious Jewish leaders today who speak of God's glory while rejecting Christ.
At the midpoint of the Tribulation, after the two witnesses were raised and ascended to heaven, a great earthquake struck Jerusalem. A tenth of the city fell and seven thousand were killed. The remnant was frightened and gave glory to the God of heaven. Les Feldick notes that God had their attention, but their response was driven by fear and the overwhelming events they had just witnessed, not by saving faith in Christ.
Les is clear that they did not. The remnant fled Jerusalem to their place of safety, but they went out in unbelief concerning the Messiah. They had been practicing temple worship for three and a half years and still could not recognize that Jesus was the Christ. They could give glory to the God of Abraham, yet they rejected the Christ. Acknowledging the God of heaven did not open their eyes to Jesus.
Les warns his classes to be careful. A religious Jew today has no trouble giving glory to God, but the issue is whether they recognize Jesus as the Christ. Giving glory can be a fear reaction, and Les says he does not embellish the fear concept. Fear may prompt a person to seek God's saving grace to escape the horrors coming on the earth, but salvation comes by partaking of God's salvation, not merely by being frightened or ascribing glory to God.
The Two Witnesses at the Midpoint
Les sets the midpoint context: the two witnesses prophesy for 1,260 days and are killed, then called up to heaven just before the earthquake of verse 13.
The Remnant Flees in Unbelief
Les shows that while the remnant gives glory to God, they are fleeing Jerusalem in unbelief concerning the Messiah, just as religious Jewish leaders today speak of God's glory while rejecting Christ.
Earthquake and the Fleeing Remnant
Les describes the physical upheaval at the midpoint and identifies the remnant as Jews fleeing Jerusalem who give glory to God.
The Same Hour Sequence
Les connects the ascension of the two witnesses with the 'same hour' earthquake and notes the slain are predominantly Jews in the Jerusalem area.
The Whole World Sees the Supernatural
Les notes the supernatural ascension of the two witnesses will be witnessed worldwide, and the earthquake follows at the same hour at the midpoint.
Glory to the God of Abraham—Still No Christ
Les explains that the fleeing remnant can give glory to the God of Abraham and yet remain ignorant of Christ, so their acknowledgment of God is not saving faith.
Fear and the Motive to Seek Salvation
Les says fear of coming tribulation may prompt a person to seek God's saving grace, but he does not turn fear itself into salvation; deliverance comes by partaking of God's salvation.
Be Careful: Glory to God Is Not Salvation
Les warns his classes not to assume that giving glory to God means salvation, because the remnant had practiced temple worship for three and a half years but still had not recognized Jesus as the Christ.
Revelation 11:13: And the same hour was there a great earthquake, and the tenth part of the city fell, and in the earthquake were slain of men seven thousand: and the remnant were affrighted, and gave glory to the God of heaven.
This is the verse at the center of the question, showing that the remnant responded with fear and glory to God without the text calling it salvation.
Because giving glory to God is not the same as recognizing Jesus as the Christ. Les Feldick teaches that the remnant fled in unbelief and had practiced temple worship for three and a half years without acknowledging Jesus. Their glory to God was a religious and fearful response, not saving faith.
A great earthquake struck Jerusalem at the midpoint of the Tribulation, a tenth of the city fell, and seven thousand were killed. The remnant was affrighted, and Les says God had their attention. Their glory was a response to the terrifying events, not a statement of salvation.
No. Les repeatedly warns that religious people can give glory to God while rejecting Christ. The escape from coming horrors is by partaking of God's salvation, not by being frightened or by ascribing glory to the God of heaven.
