6. THERE ARE MANY WHO DENY GOD & HIS SOVEREIGNTY, BUT THEY WILL NOT REMAIN IN THAT STATE FOREVER.
Exodus 5:2 - "And Pharaoh said, 'Who is the LORD, that I should obey His voice to let Israel go? I do not know the LORD, nor will I let Israel go.'"
Pharaoh had no interest in Jehovah or in submitting to His will. But, Pharaoh would learn and suffer greatly for his continued rebellion against the only true and living God! The same is true today with those who have no desire to know God or serve Him. Their rebellion will lead to great suffering both at the Judgment and even before.
7. TO MAKE WORK MORE IMPORTANT THAN GOD'S WILL IS A MISTAKE.
Exodus 5:4,5 - "Then the king of Egypt said to them, 'Moses and Aaron, why do you take the people from their work? Get back to your labor.' And Pharaoh said, 'Look, the people of the land are many now, and you make them rest from their labor!'"
Pharaoh didn't care about God's will, but Christians today must. It is regrettably the case that sometimes duties conflict with each other. We need to provide for our family (cf. I Tim. 5:8) and we need to assemble with the saints (cf. Heb. 10:24,25). In our culture, sometimes people are required to work on Sunday mornings (a police officer, for example). If such is the case, that person will be present Sunday evening to worship if at all possible (which is a fundamental reason for having a Sunday evening assembly). However, if one's job prevents him from regularly gathering with the saints any time on the Lord's day, it would be wise to seek different employment. One who is unwilling to do this has misaligned priorities.
8. WHEN EFFORT IS MADE TO DO GOD'S WILL, OPPOSITION WILL OFTEN BE ENCOUNTERED.
Exodus 5:17,18 - "But he said, 'You are idle! Idle! Therefore you say, "Let us go and sacrifice to the LORD." Therefore go now and work; for no straw shall be given you, yet you shall deliver the quota of bricks.'"
Pharaoh opposed Israel strongly regarding the idea of leaving Egypt (even temporarily). Today, a Christian may have to deal with opposition from his boss, his friends, or even his family, but such opposition must be overcome. Others will sometimes make it difficult for us to obey the Lord, but we must endeavor to do what is right regardless of the opposition we face.
9. AGE IS NO INDICATOR OF USEFULNESS TO THE LORD.
Exodus 7:7 - "And Moses was eighty years old and Aaron eighty-three years old when they spoke to Pharaoh."
This is true on both ends of the spectrum, whether young or old. Moses did his greatest work in the last third of his life. If blood still courses through a Christian's veins, there is work for him or her to do in God's kingdom, regardless of age (cf. I Tim. 4:12; Titus 2:1-5).
10. THE WICKED WILL MAKE ALL SORTS OF PROMISES TO GOD WHEN THEY ARE DESPERATE.
Exodus 8:28 - "So Pharaoh said, 'I will let you go, that you may sacrifice to the LORD your God in the wilderness; only you shall not go very far away. Intercede for me.'"
Pharaoh made many empty promises while begging for mercy, but then his heart hardened time after time and he refused to honor his word (cf. 8:32). We must be careful to always be people of our word before both God and men (cf. Matt. 5:37). Human nature is such that we are tempted to make great pledges of devotion and service when in a bind but then following through when the crisis has diminished is harder.
