The earth is satisfied by the fruit of his work.

Psalm 104:1-35
Praise God the creature.
The earth is satisfied by the fruit of his work.
Wine that gladdens the heart of man, oil to make his face shine, and bread that sustains his heart.
How many are your works, O Lord! In wisdom you made them all; the earth is fill of your creatures.
The lions roar for their prey and seek their food from God, man goes our to his work, to his labor until evening. These all look to you to give them their food at the proper time.
May the glory of the Lord endure forever; may the Lord rejoice in his work.
I will sing to the Lord all my life; I will sing praise to my God as long as I live. May my meditation be pleasing to him, as I rejoice in the Lord.
Praise the Lord, O my soul.
Why?
All of the creature are good, these are the work of God. All of his creature look to God to give them good at the proper time.
This wonderfully pictorial psalm to God the Creator and Sustainer of all has parallels in texts from Egypt to Mesopotamia. The psalmist conjures up the marvels the grandeur, the detail of the earth and its creatures, sky and sea and moon - the perfection and completeness of God's work in creation. All is summed up in verse 24. The whole of God's creation depends on his unfailing provision.
Psalmist see the wonder of God's hands and his creatures, so he will sing to the Lord all his life.
Even the meditation be pleasing to the Lord, let our mind and thought are righteous and with love, the Love please with our mind and deed.
Wine, Oil and bread all are good to man. All are the creatures of the Lord.
How?
I will praise God all my life. May the glory of the Lord endure forever and may my heart, my mind and my strength be pleased before the Lord.
