For anybody out there who may be having trouble with the "belief" thing, have I got a quote for you:
And, you know something? If it turns out that God doesn't exist and that your soul is not immortal, you will still have had the best life you could possibly have had.
The more you succeed in loving, the more you'll be convinced at the existence of God and the immortality of your soul.
This one is win-win, folks.
