not everything in that quote is true:
sorry to break it to you.. but everything won't be amazing. it's true. there will be some pretty crappy moments in your life, times when you feel down & don't know if you'll ever cheer up, times when the whole world feels like its crumbling all around you... unfortunately, we're not immune to trying & testing times.
but there's truth in that quote:
but because there is a god that absolutely loves & adores us... things are amazing. there is hope for every dark moment in your life. there is joy for every sad season you'll ever go through. and there is a peace that will wipe away any fear you will ever face. and that's what's so amazing about life.
don't worry... you'll hate life sometimes, you'll cry about it, you'll not know what to do sometimes .. and yet, everything will turn out amazing when you remember that there is more to life than that. live every moment with the knowledge that god knows exactly what you're going through; he knows exactly how to help you through it. and he'll know how to turn any bad day into an amazing one.
