It excites the magnitude and the majesty of the Lord, his goodness and his mercy, his power and his justice. It talks about benevolence Divine Providence which extends to every creature and especially to every human being. The magnitude of god is attest by the beauty and the immensity of universe that he creates. ” The heavens declare the glory of God and the firmament manifest showeth his handiwork ” Behold the whole Nature fills the man with wonder and admiration for the Creator – ” ” How many are the things you have made ! You have made them all with wisdom ” (104 :24).

Nothing can be compare to Tehilim when it’s a question of exhaling his heart, of awakening devotion that move the soul, to explain his gratitude or to request comfort.
Our wise man told that psalms have the approval of God to such an extent that their simple recitation with deep worship (even if a part of the words are not understood). He is pleasant and can often cause a miraculous help when all the other efforts failed.
