God is long-suffering because He wants everyone to be saved.
The Egyptians in the Old Testament served many Gods. Each of the ten plagues was a judgment against the gods of Egypt:
1. The water turned to blood speaks of death hovering over this earthly scene.
2. The frogs suggest the pride and self-sufficiency of the children of this world.
3. The plague of lice speaks of the uncleanness and filth which issue from the lusts of the flesh.
4. The swarms of flies suggest how that the wicked are of their father, the devil. Beelzebub means "lord of the flies."
5. The murrain of cattle tells us that the service of the natural man is corrupted at its source.
6. The boils and blains give a description of the unregenerate. Compare Isaiah 1:6.
7. The hail with lightning running along the ground symbolized that the wrath of God abides on the disobedient.
8. The locusts which ate up all the vegetation pictured the spiritual barrenness of this world.
9. The dense darkness shows how the world is separated from Him who is light.
10. The death of all the firstborn tells of the second death which awaits all whose hearts are hardened against God.
God is long-suffering because He wants everyone to be saved. Since these plagues fell on Egypt, God has been patiently waiting for men to repent of their sinful ways. 2 Peter 3:9, “The Lord is not slack concerning His promise, as some men count slackness; but is long-suffering to us-ward, not willing that any should perish, but that all should come to repentance.”
May God help us to accept Him as our Lord and Master before Judgment comes upon this world. 2 Peter 3:7, “By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of ungodly men.”
