You might not, but i still do,
You can say the same for making idols, of his son jesus christ when he was on the cross, putting that on your wall & praying to it which is not good since he is not there, it was made with tools & hands of a human & NOT by the measurements God told you to use & items he told you to use.You might say its to give glory to him for him dying for our sins, but to him its not good in his eyes, Its not what is good in our eyes but what is good in his eyes, so for me getting a tattoo something that i wont be able to take away, erase, or remove is something i dont want to do since what if he dont like them? I wont be able to remove it.
Plus i made a promise i wont get a tattoo to him (i think i made it to be sure i dint get a tattoo ... i dont really remember but thats the only reason that pops into my head right now) & when you make a promise to God you have to keep it. =)
& how are getting tattoos giving glory to God?
Instead why not go out & spread the word & gospel of God? Why not try & help homeless across the world or near you & tell them about God, buy them a bible. Thats a WAY better way to give glory to him & for a fact you will know a long with everyone else will know that that is something good in his eyes =D
