In Jobβs day, everyone knew that God was rewarding good behavior with things like wealth and good health (Job 1:1-3). Thatβs why Jobβs three friends all told him, in so many words, that he must have sinned to have incurred theΒ lossΒ of his health and wealth. This is also how God dealt with the people of Israel under the law (Lev. 26; Deut. 28). In such cases, God would use Satan and his host to effect the punishment (1 Kings 22:22; 1 Chron. 21:1), as well as the natural wickedness of men (Isa. 10:5-7).
But we are not under that kind of conditional blessing because we are not under the law, we are under grace (Rom. 6:14,15). Today God blesses usΒ up front with βall spiritual blessingsβ in Christ (Eph. 1:3), and then beseeches us to walk worthy of them (Eph. 4:1; Col. 1:10). That means that pandemics and natural disasters are not Satanβs doing, they are just the result of living in a creation that is cursed by sin (Rom. 8:22, 23). Today Satan is βan angel of lightβ (2 Cor. 11:14), and his devils are βministers of righteousnessβ (2 Cor. 11:15). They are busy teaching βdoctrines of devilsβ (1 Tim. 4:1), not wreaking havoc in the material world. source
