Second Guessing?

What's up with that? Second guessing decisions I'm trying to make, I mean when wanting to obey God's guidance. I seem to do it all the time.

Imagine. The Bible says "God told Abram to go to a land I will show you and then gave him a promise that He would make him a great nation".

Okay. I always wonder how God did that exactly. Did Abram know who God was before God told him to go to a land that He would show him? Was it a vision, was it a face-to-face conversation, was it with thundering and lightnings and earthquakes that God made his Will known to Abram?

No one knows.

But Abram obeyed! It seems he thought, that's a good idea. He packed up and left. That's all we know. Second guessing... Not so much.

Fast forward...

Abraham. The Bible tells us God told him to go and sacrifice his son, his only son with Sarah. The miracle child of their old age. On Mount Moriah, 3 days travel.

Was it a vision, was it a face-to-face conversation, was it with thundering and lightnings and earthquakes that God made his Will known to Abraham?

No one knows.

So Abraham set out. He had 3 days to think about what God had told him to do. Second guessing? I don't know. 

What do you think?
