What is a human being, what purpose does he serve? What is good and what is bad for him? The length of his life: a hundred years at most. Like a drop of water from the sea, or a grain of sand, such are these few years compared with eternity. This is why the Lord is patient with them and pours out His mercy on them. He sees and recognises how wretched their end is, and so he makes his forgiveness the greater. Human compassion extends to neighbours, but the Lord's compassion extends to everyone; rebuking, correcting and teaching, bringing them back as a shepherd brings his flock. He has compassion on those who accept correction, and who fervently search for his judgments.
The core of this passage is the nothingness of human beings like a drop of water in an ocean as compared to Almighty God. God is patient with his creatures! Where there is sin, grace abounds!
Man, at many occasions, in time immemorial has turned his back from our Merciful and Forgiving God. But we have a capacity to learn our lessons.
History repeats itself most of the time. God is the Lord of history. Our life is on His Hands. Come let us worship the source of our salvation. In Him, our life is secure no matter what happens.
