Hmm, well if we look at it from an OT-NT point of view, what we must realise is that Christ is the Word, IE He is the OT incarnate, right? Everything that has been demonstrated in the OT has been brought together in a very personal and intimate way in Christ. Now, that means that if we were to visit Him, and ask Him about Job, for example, He may well say, ‘Ah yes, I remember that part, he had hardly eaten that day! Boy, that was a shock for him!’ (or something).
I suppose that the reason as to why it is Yahweh is because He is who He is. ‘Yahweh’ means ‘I AM WHO I AM’. It doesn’t matter if we find out the earth and the heavens has a creator, or that there is love in the world, and promises to keep, they all point to Him. I think the dilemma is when someone says, ‘X created the world! He is God!’ and you respond with,
‘Ah no, actually, it was Yahweh.’
‘How can you tell? What proof is there that Yahweh created the world rather than X?’
Then I suppose it is a matter of truth. God, IS truth. So, if the earth exists, then it is true, and because God IS truth, He created it. God alone, IS.
Which is why X couldn’t have created the world. If you have a slight doubt in God’s truth, then ask the person the name of his god. We have truth, and love, as a name. We have someone who simply is who He is, and that is the one Lord, the Eternal Father, one in three and three in one with the Blessed Trinity, along with Jesus Christ, His only Son, who loves us and died for us, and the Holy Spirit, who brings that truth to our lives and hearts. It’s all in a name.
For all we know, they simply got the name wrong. We have Yahweh, and that is a pretty strong name, isn’t it?
