I think that if a person really wants a tattoo, s/he should wait until they’re married. The reason is that once you are married, the husband’s body belongs to his wife and vice versa. If you have put a tattoo on your body before you even met your future spouse, you may have spoiled your body for them. I am glad that my husband doesn’t have a tattoo. I don’t like them. I don’t like how they look, and they spoil God’s creation for me. That’s my personal opinion, and I’m sure there are other people who feel the same way. They have become so popular now that I feel that people should really consider this before getting one. I don’t think it is fair or wise to get one before you are married. If you still want one after getting married (to the one that God has chosen for you) and your spouse doesn’t have a problem with it and even likes the idea, and you have checked with God, then go ahead.
That’s just what I think. I know God does different things with different people. But if you have a desire to get married in the future and you think that God is preparing you for that, then wait on the tattoo until after marriage.
