Does this scripture include even the cross???
Deu 4:12-16.....You heard the sound of the words, but saw no form; you only heard a voice......Take careful heed to yourselves, for you saw no form when the LORD spoke to you at Horeb out of the midst of the fire, lest you act corruptly and make for yourselves a carved image in the form of any figure.....
The cross is not a graven image of God, for He is saying they saw no form of Him, so they should not make a graven image to represent Him and worship it, for the graven image is certainly not God's image neither is it Him.
The heathen had graven images to represent their God in visible form, but God said do not do that for you do not know what He looks like, and a graven image is not Him.
The cross is not an image of God, but what Jesus was on to give us salvation.
But should a person wear a cross, and if they do should they have a cross without Jesus on it, for He is no longer on the cross, and if they have Jesus on it is that a misrepresentation of Him for He does not look like that.
Should they have a picture of Jesus even though they do not worship it, for that picture they have is not Jesus for He does not look like that, and they do not know what He looks like, so is it wrong to misrepresent Jesus by a picture that is not Him.
I think we should not have any images at all, but in the Old Testament they had images of things, but not of God.
If you think mentally of the cross, and believe what Jesus did, what good is an image of the cross unless you want to show your faith, and belief, to other people as many do by a necklace of a cross, or to show their love to God because of the cross.
