Of the evils that infect God’s world (moral and spiritual perversity, waste of good, and the physical disorders and disruptions of a spoiled cosmos), it can summarily be said:

1. God permits evil; (Acts 14:16)

2. he punishes evil with evil; (Ps 81:11-12 Rom 1:26-32)

3. he brings good out of evil; (Ge 50:20 Acts 2:23 4:27-28 13:27 1 Cor 2:7-8)

4. he uses evil to test and discipline those he loves; (Mt 4:1-11 Heb 12:4-14)

5. and one day he will redeem his people from the power and presence of evil altogether. (Rev 21:27 22:14-15)
