FROM fervent devotion is born gratitude, for none can thank or praise God perfectly if he is not fervent and pious. We should thank God for everything here below, that we may be able to thank Him eternally above. Those who praise not God here, will be mute eternally. To praise God is the most joyous and delicious employment of the loving heart. There is no limit to the praises of God, for therein is our salvation, and we shall praise Him eternally. Now hear a comparison, by which you may understand the exercise of gratitude. When the summer approaches and the sun mounts, it attracts the moisture of the earth along the stems and branches of the trees, whence come green leaves, flowers, and fruit. Even so when Christ, the eternal sun, rises in our hearts, He sends His light and heat upon our desires, and draws the heart away from all the manifold things of earth, creating unity and inwardness, and makes the heart grow and become green by interior love, and makes loving devotion flourish, and makes us bear the fruits of gratitude and love, and preserves these fruits eternally in the humble pain of our inability to praise and serve Him enough. Here ends the first of the four chief kinds ot interior exercises, which adorn the lower part of a man. HOW TO INCREASE INWARDNESS BY HUMILITY BUT in thus comparing to the splendour and power of the sun the modes in which Jesus Christ comes, we shall find in the sun another virtue or influence which makes the fruit more early ripe and more abundant. When the sun rises to a very great height, and enters the sign of the Twins--that is to say, into a double thing, but of the same nature, in the middle of the month of May, the sun has a double power over the flowers, herbs, and all that grows upon the earth. If at that time the planets which rule nature are well ordered according to the season of the year, the sun shines brightly on the earth, and attracts the moisture in the atmosphere. Hence are born dew and rain, and the fruits of the ground increase and multiply. Even so when Christ, that bright sun, rises in our heart above all other things, and when the requirements of material nature, which are contrary to the spirit, are well regulated according to reason, when we possess the virtues as I have said above, and when, lastly, we offer and restore to God, by the ardour of charity, and with gratitude and love, the delight and peace which we find in the virtues, from all these are born, at times, a gentle rain of new internal consolations, and a celestial dew of divine sweetness. This dew and rain make all the virtues increase and multiply day by day, if we put no hindrance in their way. This is a new and special operation, and a new coming of Christ into the loving heart.
