If Paul even weeps over many who call themselves Christians, he always rejoices in the Lord; in Him is that which nothing can alter. This is not an indifference to sorrow which hinders weeping, but it is a spring of joy which enlarges when there is distress, because of its immutability, and which even becomes more pure in the heart the more it becomes the only one, and it is in itself the only spring that is infinitely pure. When it is our only spring, we thereby love others. If we love them besides Him, we lose something of Him. When we are weaned from all other springs, His joy remains in a It its purity, and our concern for others partakes of this same purity.
