“For this time I will send all my plagues on you yourself, and on your servants and your people, so that you may know that there is none like me in all the earth. For by now I could have put out my hand and struck you and your people with pestilence, and you would have been cut off from the earth. But for this purpose I have raised you up, to show you my power, so that my name may be proclaimed in all the earth.” – Exodus 9:14-16
The purpose of all which we call good and all we which we call evil is to bring glory to God. Both the wicked and the redeemed alike, are raised to life to bring glory to the Creator (Prov 16:14; Rom 9:17). Commonly, it is asked, how a loving God could allow wicked things (Hitler, Ebola, starvation, etc.) to flourish in the world. All creation is wicked without the blood of Christ.
While God is not the author of evil, he allows it to bring himself glory and to enable his limitless grace and justice to be seen more clearly. Douglas Stuart said, “This passage is something of a proto-evangelium, a call to the whole world to appreciate what the plagues ultimately showed, that there is one God in control of all things and that he alone can save.” There is none on earth like the Lord and he has called his disciples to proclaim him to the nations.
Before the Lord called down the seventh plague: hail, Moses was instructed to warn Pharaoh. Some in Pharaoh’s company followed Moses’ warning and saved their animals and slaves from God’s wrath. Others did not. All of mankind is given a chance to repent. No man who ever desired to follow the Lord was ever denied the chance.
Yahweh creates the repentant and unrepentant alike. All humankind has been put in place to serve God’s purpose to bring himself glory. Man was created and placed in his geography, station, and time so that God’s glory can be spread to all the nations. Each man exists, whether believer or not, to play his part in bringing God greater glory in the earth.
Missions is a call to Christ’s church go into the world and increase the proclamation of God’s name among the nations. A missionary serves, not because he loves the lost, but because he loves the Lord.
