When we underestimate life, it always leads to something we can never think of. Just as you've said;
Life has shown that it has no respect for anyone.
Life doesn't care maybe you are young or old, when it has one's time, it dishes out the best goodies in health, wealth and a lot of other things.
Exactly, it has no respect for anyone and anything at all can happen to anyone. I just feel that we're living at the mercy of the things we don't know and have control over. If God doesn't plan or guard someone, then whatever one is doing is actually in vain.
Yes, we sure are, which is why we need to thread carefully. That's right, God always needs to be put first.
