Chances are something terrible has already happened to you and it has you questioning yourself, doubting who you are and what you believe. That is not unusual. Suffering naturally produces doubts.
But, allow me to say something about that and listen to me very carefully - what happens to you does not say anything about you but how you respond does. You see, life is 10% of what happens to you and 90% of how you react to it. The rotten things that happen to you does not diminish your worth or value. You are still a precious soul, loved by God, with gifts to give to the world. Do not doubt that. Never doubt that.
