The video itself is well done, in my opinion. I appreciate it when someone is succinct and straightforward when making a video explaining their stance on something.
The thing about the stance itself, is that it is based on cherry picking out of Leviticus, which has other rules/sins listed that are typically overlooked by the same people insisting that Leviticus can be used to demonstrate that tattoos are sinful. They are typically overlooked because they are old covenant rules, some of which Jesus Himself explained were irrelevant.
For an example, compare Leviticus 11 to Matthew 15:1-20.
However, Jesus also emphasized that intention was important.
For example, consider Luke 12:10-17 or Mark 3:1-6.
So this is why I believe that my own tattoo which I got when I was younger, was a sin for me to get, due to the nature of it and my motive behind it (pagan tattoo, got it in an impulsive and slightly intoxicated state, an act of rebellion against God, etc).
However, at the same time, I don't think you'll have much success convincing people on the matter of tattoos by cherry-picking out of Leviticus, for the reasons I already mentioned.
Rather I think if someone is considering a tattoo, and they are a Christian (which hopefully means that they want to do their best to follow Christ's teachings), then it is better to refer to Jesus' own teachings for guidance.
1. What is the intention behind getting the tattoo?
2. Will the tattoo help to glorify God or will it glorify something/someone else?
3. What are you not doing with the money that you are instead planning to spend on the tattoo? In essence, do you know people/someone in need, yet you spend the money to decorate your body instead?
I think that these are deeper spiritual questions that can help people to gradually move in a Godly direction with their lives, through spiritual introspection.
But the same questions could be applied to a great many other things, which is perhaps why some people are so hesitant to use them, as opposed to cherry picking out of Leviticus.
For example, even something like buying new furniture for your house could bring up the same questions. Are you more concerned about wanting flattering material things, more concerned about spending money to make your temporary, worldly properly look nicer, than you are concerned about helping those in need and giving the glory to God in the process?
So I think that is part of why so many prefer to cherry pick, rather than doing the deeper, more complex spiritual work that comes with applying Jesus' teachings to our lives.
Cherry picking out of Leviticus would allow one to say, "Well I don't wear mixed linens, and you do, so therefore I can call you on out on this without having to worry about you pointing out my own clothing."
But offering Jesus' teachings for guidance means that we would also need to look at every aspect of our own lives at the same time. However, I think this is the best approach. It can also help us to avoid the pitfall described in Matthew 7:3, if we instead focus on fellowship using Jesus' teachings, in which we share with each other how those teachings could help us improve our own lives. I think that spiritually this is much better for us all around.
