"Remember this, and be assured ..." (Is 46:8 NASB)

Israel had several problems that God was trying to deal with when he sent his messages through Isaiah. One which we may take for granted today is the supremacy & singularity of God himself.

Isaiah 46:8-11 (NASB)
Remember this, and be assured;
Recall it to mind, you transgressors.
Remember the former things long past,
For I am God, and there is no other;
God, and there is no one like Me. ...
Truly I have spoken; truly I will bring it to pass.
I have planned, I will do it.

I don't think this is an issue the world has quite learned to cope with yet. Growing up on a pew, I was raised with God's word and the primacy of his rule & authority. But the world offers many options now as it did back then. The general idea today is, "I believe in an Almighty God, and I believe that all the world, whether they be Muslim, Christian, or any other religion, prays to the same God".

The LORD heavily stressed to the Israelites that he stood alone as God and that he is a jealous God (Ex 20:5).

However, God also expresses his reach, care & concern for the people he has created in Isaiah 46:1-4 (NASB):
Bel has bowed down, Nebo stoops over;
Their images are consigned to the beasts and the cattle.
The things that you carry are burdensome
A load for the weary beast.
They stooped over, they have bowed down together;
They could not rescue the burden,
But have themselves gone into captivity.
Listen to Me, O house of Jacob,
And all the remnant of the house of Israel,
You who have been borne by Me from birth
And have been carried from the womb;
Even to your old age I will be the sam,
And even to your graying years I will bear you!
I have done it, and I will carry you;
And I will bear you and I will deliver you.

This isn't a LORD who stands apart and away but reaches down to carry our burdens.
This isn't a wooden idol which is heavy on an animal, but a God who has bourn us since our birth.

There's still a bit of confusion out there: Is there another God? Are there lesser gods? Is Jesus really God or a lesser God? Are there other sources of hope?

There's still a lot of options for us to trust in: Some trust in empirical evidence ... or their own experiences ... or in a collection of faiths, distrusting any one on its' own.

God reminds us that we can trust in him as a single and supreme God.
God reminds us that we can trust what he's said:

For I am God, and there is no other; ...
Truly I have spoken; truly I will bring it to pass.
I have planned, I will do it.
Isaiah 46:9-11 (NASB)
