"Whoever regards one day as special does so to the Lord. Whoever eats meat does so to the Lord, for they give thanks to God; and whoever abstains does so to the Lord and gives thanks to God. For none of us lives for ourselves alone, and none of us dies for ourselves alone. If we live, we live for the Lord; and if we die, we die for the Lord. So, whether we live or die, we belong to the Lord. For this very reason, Christ died and returned to life so that he might be the Lord of both the dead and the living" (Romans 14:6-9, NIV).
I have a tattoo. For most who don't know me, you could probably care less. Others might be turned off as to why or how I could possibly violate God's Holy Word in Leviticus, "You shall not make any cuts on your body for the dead or tattoo yourselves. I am the LORD" (19:28). Understanding this verse in its proper context that it was in regards to idol worship and the like, will never satsify some. I have sinned. It is easy to look at people's bodies and rush to judgment as to why people do what they do, but the question could be asked easily of the one rushing to judgement. "Why are you quick to assume?"
In everything you do, the Bible calls you to do it for the Lord. Let God be the "why." Yes, my tattoo represents that very passion. I decided once upon a time to have my wedding ring tattooed to my finger. Most people will never see the ink. I wear my ring on top of it. I got the tattoo to remind myself of the permancence of the covenant I have made with my wife and God. I didn't get it to bring attention. I did it to direct attention from me to God. Why say it here and now? It is a reminder to me and to all that in everything we do, do it for the right reason. God has not called you to live life going through the motions. One who gets a tattoo for the wrong reasons of directing attention to themselves is no different from the one who takes Holy Communion with no regard for who or why it celebrates, but mindlessly goes through the motions.
Do what you do as unto the LORD, not as unto religious obligation or public self-righteousness. Grow closer to Jesus. THAT is the call God has placed within you. Don't allow yourself to get caught up in the distractions that take you off track from pursuing Jesus. Before assuming why someone does what they do, ask yourself this question. 'Why do you care so much?" Let your REACTIONS be worshipful to God as you observe and question worship-nature of someone else's actions. If you can answer that is the "why" for all that you do, don't be quick to assume differently for others who also identify with Jesus. If it is a matter of real sin, bring it up. If it is a matter of difference of opinion, go ahead and put it down. Focus on what brings you closer to Jesus. Let Him be the "why" for what YOU do. Leave the rest to Him.
