Promises, promises

I just learned something...mm, perhaps had more of a revelation. Okay, so I'm looking up righteousness and I'm finding all these passages and it's very helpful, but I remembered one passage that talked about righteousness that no concordance had mentioned. It was Hebrews 11. So, I'm reading through this passage and finding out what made them receive credit to righteousness and I see that it is their faith in God. Well, then I go do something else and as I'm "chewing the cud" I come to realize that Abraham, Isaac, Jacob, Noah and all the other people mentioned are having faith. Faith in what? Things hoped for not yet seen. Okay, but then I thought, well "how did they know that something "unseen" was coming? Of course, God told them.
And most of the time, God used promises to make sure that these patriarchs knew He meant business. Then, I thought, "oh wow, that makes sense. we're always told to lean on God's promises, to believe that He is faithful and will provide. We are always told to believe that God's promises are true.
Okay, so we've had the Bible for years (literally) but back then, Abraham (for example) only was given like three promises. All he had to do was lean on three promises. It was simpler, not easier, but simpler. So, now I say, well hey there are TONS of promises in God's word. Wow! Why didn't I think of that before? God wants us to trust in His promises, just as Abraham trusted in God's promises. Why are we so blind? Why do we miss that? I want to live trusting in God's promises. Because a promise is real, it's there, it's never-ending. I mean, espcially if it's with God...it's binding. Wow! We should trust in His promises so much more.
