When you have God and the promise of eternity wearing a seatbelt doesn’t diminish trust in His plan.
Just shows that you appreciate that He gave us reason and intellect to help cherish and value the life He gave us.
It's a matter of degree. Reasonable caution is one thing; blind panic another.
Wearing a seatbelt can kill or save, depending on the physics of the accident or collision. You might need a different argument.
