What is the meaning of tattoos that has not changed?
From ancient times, tattoo's or the cutting of one's skin has been associated with paganism and is a satanic aspiration. We are to be different from the world. Be Holy for I am Holy is found in where? 1 Peter 1:16; but where is it quoting it from? Where is that phrase that is written in the "New" Testament could possibly come from? Well, it can be found in the beginning of Leviticus 19:2 for one place, among several others in Leviticus. But also at the end in Leviticus 19 in verse 37 it exhorts us to follow his commandments. So in between being told to be holy and to follow his commandments, is a passage saying not to cut your skin. Well I am sorry, God is much smarter then I am, and if he said once, and he only has to say it once to not do it, I believe he knows what is best for me and trust him unfailingly.
The subtle selling of tattooing under the pretext of it being a "witness" tool with the guise of more and more Christians are doing it makes it no more right.
And it goes back to the beginning with Adam, "Did God really say...?"
Malachi 3:6
“For I, the Lord,
do not change; therefore you, O sons of Jacob, are not consumed.
If you look really hard, strong parallels can be made between the theory of evolution and the theory of dispensationalism. If you'd like, I can quote a comparison I heard for amusements sake.
