There is a space of time that God gives men to repent of their wickedness (Revelation 2:21).
How long is this interval of grace?
No man knows–for God determines our appointed seasons and the bounds of our habitation (Acts 17:26)–and if we do not repent in the space provided, the heavens will turn to brass [Deuteronomy 28:23):
To be encouraged of the certainty of God faithfulness in blessing the faithful, read Deuteronomy 28:1-14.
To be terrified of the certainty of God’s wrath and cursing against those who persist in wickedness, undeterred by the Holy Spirit’s warnings, read Deuteronomy 28:15-all.
