Dream Come True

There are days when I realize that much of my life is a dream come true. I just have no complaints. It's not that it's perfect, it's just more than I thought possible for me. I didn't expect to know joy like this. I feel as though I have an abundant life. You would think I would find comfort in this. I don't know what happens, but I find that I become anxious. It's too good to be true. It's as if I wait for the inevitable tragedy. What will it be? This is so sad. Why are we so quick to sabotage our lives? What does it mean to rest in Christ? What does he mean when he says "my yoke is easy and my burden is light"?
