I find it easier to meditate on the word 'exalted' than the phrase 'most high'- maybe because i don't have a series of traditional 'gods' in my psyche whom i can imagine God being above. However, if I think of the spiritual realm (which I don't feel particularly versed in/aware of), its quite easy to see that GOD is Most High- above any other spiritual force.
Of course there is the correlation between the belief system of Abrams day- the multiplicity of gods- and that which we worship in our current culture, which I guess can be summarised by the concept of consumerism and acquiring material wealth and status (which boils down to glorifying MYSELF).
It is helpful to remember that God is HIGHER than these things we pursue, that ultimately the things we so often turn to (financial security, having nice things, others perception of us) cannot and will not save us, neither are they the Creator of life! In fact, perhaps they are part of the road to death (separation from God).
I find the the Pete Sanchez/Ps 97 song a great thing to meditate on & will be mindful of Gods HIGH-NESS as I pray this week.
