Blessed are the pure in heart, for they shall see God. - Jesus
The most beautiful of all blessings is reserved for the pure in heart: seeing God.
Here, among all the blessings that Jesus proclaims, is one blessing that I do not think could possibly be any other way. If we are small and self-centered, we don't even see the people around us, not really. If our lives are all about ourselves, then it's not just the words of God that we don't hear, but even the words of the person talking to us. "He who has ears, let him hear" could be a fair warning whenever anyone is talking to us. Whenever we are self-centered, we do not see our neighbor, we do not hear our own family, we do not notice the person sitting next to us. The beginning of a pure heart is to love our neighbor. The stronger we become in love, the more we are able to see what is around us -- to see who is around us. (There are ways in which love is blind, but hatred is much blinder. And indifference is nearly defined by willful blindness.)
As for seeing God: God's presence is all around us, but when we become impatient or frustrated we do not see it. It is in our quieter and kinder moments that we notice it. Even in this world, the pure in heart see more.
And in the world to come ...
