A final word of exhortation. Exodus 7:1-7 When God spoke again to Moses, He emphasized to His servant that His message was being delivered through Moses. Then Aaron was to relay that message verbally to Pharaoh. It’s possible that Moses did not speak directly to Pharaoh and that fear of Moses affected the Egyptian king. God had one final word of encouragement for Moses, reminding him that he was acting with divine authority through the signs and wonders he would perform, as well as the significance of his words.
Any person whom God uses to speak for Him must remember that we are simply people under His authority. We are not independent voices given permission to say what we want. We are passing on God’s mind and will to others, not our interpretation of truth or our opinions about it. Our role is to communicate God’s message to others in words and ways they can understand and accept if they choose. If they decide to reject what God says, they need to realize there are consequences beyond their control.
Moses didn't realize Pharaoh's hidden fear of him until God revealed it. Pharaoh saw Moses as a god, but Moses never thought of himself that way. Now he understood it was God working through him, even in what seemed like failure, and that success would come in His own time. At eighty years old, he was still learning what God was like and discovering who he was.
In each event involving supernatural signs, the words “The Lord said” or “Thus saith the Lord” were used to give Pharaoh the understanding that these signs came from a source far greater than Moses and Aaron. The great judgments, or “mighty acts of judgment,” served a specific purpose. Pharaoh and the Israelites needed to learn who God is and what He is like. His authority and power surpass that of nature, as He controls it. As the mighty Creator, He makes His creation do what He wills. He can increase or decrease natural functions as He chooses to accomplish His sovereign plans.
Sometimes, when we are feeling down and doubt what we have been called to do, God places us in a situation and mindset where He can reveal things to us, knowing that this will not lead to pride or self-exaltation. In God’s view, age does not change our obligation to follow His revealed will. Old age should have taught us wisdom and responsibility, allowing us to use our experience and seriousness to benefit every situation. It is completely inappropriate for older people to act like children or try to imitate passing fads and trends.
