How do we know God's judgment on false professors?

The judgment of God upon false professors is depicted in the stark contrast made in Scripture regarding their end. Those who kindle their own fires and rest in human constructions of faith will ultimately find themselves in sorrow, as noted in Isaiah 30:33, which speaks of the flames that God has prepared. This judgment is not always immediate; as seen in the life of many false professors, their delusions may allow them to walk through life seemingly without trouble. However, the final outcome is that they will face the reality of their unredeemed state, which leads to eternal separation from God. A sincere believer, in contrast, despite struggles and darkness, can rest in the assurance of God's grace and trust in His promises.
