How do we know God protects His people from Satan's attacks?

The passage in Revelation 12 illustrates that though Satan is a relentless adversary, God is ultimately sovereign over all, including His adversary. Revelation 12:15-16 describes how the earth helped the woman, symbolizing that God employs all creation to protect His church from the malignant schemes of Satan. This is illustrated in historical examples, such as how God controlled events during the time of Christ and Job's afflictions. Believers can therefore rest assured that Satan's influence is under God's control, and He provides protection and sustenance throughout the church's struggles, ensuring that His purposes prevail.
