(Teachings from Gita)If we were to know that the most powerful man on earth was working for our benefit and would look after our safety, we would feel so secure. Now imagine if we knew that God - the supreme one, the creator of this world, the all-powerful - was looking after us, we wouldn't have any worries! And this is the truth. Whatever God does is for our benefit. We need to realize that and have complete faith in this fact. One who does that has no fear or anger and leads a blissful life. We might term whatever happens to us as "good" or "bad" but the truth is that all that happens to us is for the good of us. Maybe we don't realize it then but in retrospect it did help us in some aspect of our life.
If you lose something, it teaches you to be more careful and not take life for granted. If you fail, you learn to work harder and not to make the same mistakes again. So the next time you think something "bad" has happened to you, sit down and take out some time to think about what does it teach you.
It's easy to believe in God when "good" things happen to you but the real test is to still believe in him when "bad" things happen to you. If you can do so then you'll see how smoothly you can sail through life.
