Seek directions from the Holy Spirit on wether you should get a tattoo and your motives.
Some Christians will say that it is wrong to get a tattoo. I don't judge right or wrong in this matter because we must always look at scripture in context and ask if the same applies today in this situation.
I am not certain that God forbids tattoos for his people today in all situations.
God forbids boasting, self harm, destruction of your bodily temple, and marking your body towards other gods and as part of anti- Christian rituals or ideals.
At the end of the day. Some Christians prefer to stay as far away from gray areas as possible but this is a personal choice.
There are some great Christians with tattoos and this does not interfere with their salvation or walk with God.
I like the last one best.
