Before this verse, the Bible gives a recap of the Israelites deliverance from Egypt. After all, their deliverance from captivity was nothing short of amazing. He split the Red Sea and they walked across on dry land!
But verse 18 says forget all that. Wait, what? Forget one of the most miraculous stories ever told, seriously? Well, don’t forget it, but think about this. A brand new thing so amazing is going to be done that you might actually forget about the deliverance from Egypt by comparison.
Honestly, I think that God is always on the brink of something new. The greatest thing is salvation, but after being saved, I think we always have to be prepared for a new thing. It’s not like the Israelites had never been delivered before, or like they had never received promises. God was saying, “Hey, there’s a new deliverance coming and a brand-new promise on the way. Get ready.”
So, what’s God’s brand new thing for you? Is there deliverance from something? Is there a new promise He has for you? Has He already begun and you do not see it? It’s possible to miss it. Just ask the Israelites.
