And we continue our faith examples with another story about Abraham. Not only was Abraham supposed to leave home, but, after a lifetime of wanting children, and not having any, God told Abraham, and Sarah, that they were going to have a son. And the son was going to be the start of a great nation. And the nation would be a blessing to the world.
And, indeed, a son was born.
Then, God said to offer the son as a burnt offering. ???
That son, who will become a great nation, and bless the world, kill him, and burn his body. ???
Does that in any way make sense?
Apparently, it did to Abraham. He did not sacrifice Isaac, but he had decided to in his heart. But God stopped him at the last moment.
Abraham believed that God could keep his promise to make a nation, even if Isaac was offered as a sacrifice. The writer of Hebrews suggests that, maybe, Abraham believed that Isaac would be raised from the dead.
And that's the point. No matter how crazy it seems, God is able, and he will complete, what he has spoken. So, faith, at its most basic, is believing, and trusting, God to do exactly what he says.
So, a large part of walking with God is knowing what he says. That is why he gave us the Bible. That is why reading, and meditating, on the Bible is necessary.
Another large part of walking with God is grabbing onto what he says, and living as if what he says is as real as gravity. And it is that real, because God said it.
