Fifth phrase:

To Him belongs all the praise means that only God deserves praise and acclaim, that everything is indebted only to Him. All bounties are His, for they come from His infinite and inexhaustible treasury.

This phrase implies: The bounties (you now enjoy) will never cease, for His Mercy’s treasury is inexhaustible. Your (current) enjoyment will never cease, for every enjoyment you are granted is the fruit of infinite Mercy. And the tree of that Mercy cannot die, for each exhausted fruit is replaced with a new one. Furthermore, offering thanks and praise for what you currently enjoy increases it a hundredfold, since every enjoyment is, in essence, a favor from the Divine Mercy and therefore 100 times more enjoyable than the enjoyment by itself. If a glorious king gives you an apple, your pleasure at such a royal favor will be superior to the material pleasure of 100 or even 1,000 apples.

Similarly, this phrase opens the door of a spiritual enjoyment 1,000 times sweeter, since it makes you consider the bestowal of bounty, which leads you to recognize the Bestower and reflect on His merciful favors that pour out continually.
