When a child is tossed into the air by his father or mother, the child laughs. He enjoys that moment. He knows that when he falls back again, his parents will hold him. This is faith. When you have faith, you become fearless.
Imagine the troubles that you had a few years ago? Do you still have them? The answer is No. Troubles come like waves, touch your lives and go away. Have this faith. And you will see that you will be able to cope with troubles easily. Believe, if troubles have come, they shall go as that is how life has been designed.
