Biblical explanation
God's original creation was "very good" (Genesis 1:31). Evil was not presented as part of God's original design. The Bible identifies Satan as a rebel against God. Revelation 12:7-9 describes a conflict in heaven and identifies the devil and Satan as the deceiver of the whole world. Isaiah 14 and Ezekiel 28 contain passages describing pride, rebellion, and the downfall of a heavenly being, although their immediate historical contexts also concern earthly kings. Human rebellion followed. Genesis 3 records the entrance of sin into human experience. Why did God not immediately destroy the rebels? Scripture indicates that God's government is based upon truth, love, and justice. The story of Job shows Satan making accusations concerning God's motives and the loyalty of His servants (Job 1:9-11). The larger biblical narrative therefore involves not merely God's power to destroy evil, but the revelation of His character and the truth about sin. At the cross, God's character and the destructive nature of sin are dramatically revealed. Romans 3:25-26 presents God's justice and mercy together. God will eventually end evil completely. Nahum 1:9 says that affliction will not rise up a second time, and Revelation 20:10-15 describes the final destruction of Satan, sin, death, and those who persist in rebellion. Scripture reveals the origin, nature, and ultimate destiny of evil, but it does not answer every philosophical question about why God permits every particular event.
Key takeaway
Discipleship applies the gospel to the whole life: body, mind, relationships, work, finances, and worship. Healthy choices and faithful habits do not earn salvation; they are grateful stewardship of the life God has entrusted to us and practical ways to serve others.
