Moses had turned to the Lord in his desperation (5:22-23), and the Lord responded with patience and grace. He reminded Moses that He was the all-powerful, unchanging, promise-keeping God of Abraham, Isaac, and Jacob. He reassured Moses that He intended to keep the covenant He made with Abraham to bring His people into the Promised Land.
Additionally, God gave Moses the content of his next speech to the Israelites: seven promises in verses 6-8 that detailed what God said He would do for His people. It is important to note that these “I will” statements are found between the bookend declarations, “I am the Lord” (v.6, 8).
When Moses delivered the message to the Israelites, they were too broken and depressed to receive it. Discouraged again, Moses prayed (v.12), “How am I supposed to convince Pharaoh to let Your people go? I can’t even convince Your people that You can make it happen!” The question is repeated in verse 30. Moses was asking a question God had already answered.
Question: How was he to confront the stubborn tyrant, motivate the depressed slaves, and lead the exodus?
Answer: Four times in this chapter God said, “I am,” indicating His power and presence with Moses. Eight times in this chapter God said, “I will,” indicating that His sovereign will was at work, ensuring that His divine plan would come to pass — no matter how the king resisted, no matter how discouraged the Israelites were, no matter how inadequate Moses felt.
Remember today that you can trust God. He is more powerful than anything that can come against you. He is present in your situation, right now. He keeps His promises. His will is going to be accomplished. He is in control. Just trust Him…and prepare to be amazed!
[Note: the genealogical section in verses 14-27 may seem out of place here, but it serves two purposes. First, it establishes the tribal lineage of Moses and Aaron just before the dramatic events of the Exodus in which God did His greatest work through them. Second, it focuses on the descendants of Aaron who would serve Israel as priests after the Exodus.]
