Is getting a tattoo a really awful sin? (christians please)?

I suggest you do not try to show your love for the Lord with a tattoo of the Holy Cross. We are instructed in the Holy Bible that our bodies are holy temples given to us by the Lord in 1 Corinthians 6:19 “19 Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; “ So we are holy temples, and our holy bodies are not canvases to be profaned with unholy graffiti, in a manner offensive to both man and God, who instructed us through the prophet of God Moses : "Do not cut your bodies… or put tattoo marks on yourselves. I am the LORD” Leviticus 19:28. Although this is Old Testament, and some Christians think they need not obey, I am not so sure myself. If the Lord does not want tattoos on His Levite Priests, is it beyond understanding that He may not want them on his Christian followers, despite the fact that there is no specific prohibition against them? I would suggest no more tattoos, even of the Lord Jesus, or of His Holy Cross, since tattoos are in many eyes such an eyesore. It could be construed as disrespectful of the Lord, even. This is just my opinion. Praise the Lord forever. Praise His Holy name. Pray for your guidance from the Lord, and good luck.
