Belief is significant to your life. Not belief in any one thing, but beliefs you hold that determine any one direction you take. 

That said, with my utmost sincerity; Christ is King. The God of peace.

What a faith we have to follow, it brings so much joy and peace, more so than any other thing, person, or belief you could hold with you.

The significance and impact on your perspective it gives you is just.. insane.. So much so, that I'm willing to give my life here on earth away to tell you that it is the TRUTH, THE WAY, IT IS THE LIFE.

I was an atheist just over about a year ago. I too found these testimonies cringe. I just have nothing of more value to add here.
