You can never laugh away your sorrow, simply because; laughter can never mask a heavy heart, Whenever the laughter ends, the grief remains. You need to first of all deal with your problems, before you can have genuine happiness.
That's why, our faith can never change as long as our feelings remain the same, it's Simple because the internal you, sustains the external. Faith is not something ready made, you have to really work for it, It comes from your own believe, decisions and actions.
You can't have genuine conviction if the things you believe in are different from the things you do.
If you want the rainbow, you have to first of all deal with the rain.
You need to start by breaking down your pride and all these false defensive walls you've built up inside, then guard your heart because they influence every decision you will ever make in life.
Surrender to what is, Let go of what was
Have faith in what will be.
