Not made with Hands

2Cr 5:1
For we know that if our earthly house of [this] tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens.

This is a phrase that repeats in the bible why is it significant?
I believe that the third commandment has two parts you shouldn't make and you shouldn't bow down to graven images.

Exd 20:4
Thou shalt not make unto thee any graven image, or any likeness [of any thing] that [is] in heaven above, or that [is] in the earth beneath, or that [is] in the water under the earth:

or to connect the thought, ' To make, is to bow down'.

The things that God has made are Good but man made things are like us faulty. that is why we should stick to making useful things like houses and not images of animals etc. to fill them. God did tell the isrealites to make images like the snake in the wilderness and the temple included graven animals and trees also the ark of the covenent had angels and maybe other stuff on it to. But these things have been taken away now because God knows that they would have been worshiped in his stead. Worship God not the things he has made and definately not the things man has made.
