Things of heaven cannot be obtained by perseverance; they are the grace of God. To open to this and trust in it is how belief is crystallized into faith. We cannot pay for it in any form, in any way, by our goodness, by our piety, by our great qualities, merits, or virtues; nothing. It is a gift, and all we can do is receive it.
The rain does not fall in a certain land only; the sun does not shine only on a particular country. All that comes from God is for all souls. Verily, blessing is for every soul; for every soul, whatever be one's faith or belief, belongs to God.
The man who tries to prove his belief superior to the faith of another, does not know the meaning of religion.
