When they heard these things they became silent; and they glorified God, saying, "Then God also granted to the Gentiles repentance to life" (Acts 11:18; NKJV)
They understood that God had granted to the Gentiles repentance to life based on this five things:
1. The Divine Vision - Acts 11:5
2. The Divine Command - Acts 11:12
3. The Divine Preparation - Acts 11:14
4. The Divine Action - Acts 11:15
They necessarily inferred from Peter's divine vision, the Spirit's command and preparation and action, that God had granted to the Gentiles repentance to life.
God did not correct them because they drew a necessary conclusion based on His divine work.
