For peace

God wants his people to live in a peaceful environment. That is why God told them to target three things in Ex. 34:13. They have to destroy, smash and cut these three things.

1. Altars ( destroy)
2. Idols (smash)
3. Pillars (cut)

Not every altar they see, not every idol they see, not every pillar they see. He did not tell them to remove them while they were in Egypt and while they were going through some pagan kingdoms. They have to remove those three things only in the promised land. 

But sadly human beings usually think that compromising with these things help them live peaceful with neighbors. 

Exodus 26:15

We have roof for the church. This roof stood on 6 pillars. One night there was a big storm. I found that some part of it has fallen down. I went near to see it. The north-east corner pillar was broken in the middle and north side middle pillar did not broke but bent down.The broken pillar lost its intensity and bent pillar lost its stability.

The plates that were made stand upright for the tabernacle were overlaid with gold around them and supported by the two silver bases on the ground for each plate. Gold and the silver are used metaphorically as the word of God. David said that the word of God is more better than gold and he also said that the words of God are more clean than the silver that was proved 7 times.

Overlaid word of God gives us intensity and the the word based life stays with stability.

A fool built his house on sand while wise man built it upon the rock. Then what about the tabernacle in the sand? The passers might have thought that the Israelites are fools. But they dont know who the actual engineer was. Its not about where you built. Even if you build it upon a sand but according to the word of God, your plates will never be broken or fall down. The word of God gives both intensity and the stability.
