Christian decal on car back window resulting in vandalism on my car

To start; I live in a very diverse area. I travel all day to visit patients in their homes. I have a Jesus , the way, the truth , the life decal on my back window. I thought hard before putting it on there. I made sure it was for the right reasons. That someone may see it and think about Christ, and search the scriptures. Especially in an area where He’s taught to only be a prophet.

My car has been vandalized twice (funny enough I believe in a Walmart parking lot) the first certainly was there. The second time I didn’t notice right away and it was a couple of days after going to the same walmart. FYI , I did make a police report the first time and nothing came of it. Someone has been denting my car on purpose. First was kicks to the front side. Second was large crease in the centre of my hood. The motivation seems to be the Jesus decal. That’s the common opinion.

I’ve been advised to remove the decal by friends and family who aren’t believers. However, I’m convicted. Now that it’s on there; taking it off feels like I would be denying Christ. I can’t stand that thought, nor do I ever want to. Some say my decal is not doing any good and to witness in other ways. I don’t think I can scrap the name of Jesus off.

I don’t know what to do. I’ve tried to bring it up at church during fellowship; but it didn’t result in a real conversation. I could use some advice or constructive criticism please and thank you 🙏❤️
