All you fussing about the trees, the focus is not on trees or even gift giving. Look at verse 2 of
Jeremiah 10, where it speaks of not following after the ways of the pagans, the same command given Israel in
Deuteronomy 12. We are called to be separate, and not use the ways of the pagan nations to worship God, for such is called an abomination. Just like false doctrines which say 'Jesus already come back and there is no rapture' and 'one person pastorialships are of the enemy', so is also the use of paganism to worship God.
