Ps 63 2I have seen you in the sanctuary
and beheld your power and your glory.
3Because your love is better than life,
my lips will glorify you.
4I will praise you as long as I live,
and in your name I will lift up my hands

The Psalmist is describing the spiritual experience as a result of speaking the law, covenants, curses, statutes, decrees and promises. The axioms transcend the physical barriers of worship. This is why he teaches that the axioms bring him pleasure that transcend his human desires. You love is better than life. When we speak the axioms we are going beyond our understanding. The apostle says that we are seeking something that we cannot understand in order to once again seek something that we do not understand.
