Thanks Gino, for your insights. Yes, I used to find the OT boring and
unrelatable too but as I matured over the years I realised a lot of it
is about foreshadowing Christ's sacrifice and that all scripture is
profitable for edification. I like your reference to Psalm 119:8 and
agree that there is so much to learn and consider. I consider the
Israelites wandering in the wilderness for 40 years, Jesus being
tested in the wilderness for 40 days, as relevant to how I lead my
life. Will I be able to pass the manifold trials and temptations in
the wilderness of this life, or fall like many of the Israelites did?
I also consider how King Saul messed up by not waiting that few more
moments for Samuel to arrive to perform the sacrifices - I might
easily have made the same mistake as Saul did.

I have not really mulled about what David was thinking through as he
penned the Psalms; it is certainly an interesting perspective to
consider. But I suspect a lot of what David wrote was somehow revealed
to him supernaturally by God, as the more I read the Psalms the more I
realise their prophetic significance. Many passages in the Psalms
could be about David as king, David crying out to God for help, or
praising God, but I see a lot of Christ the true King's voice in the
Psalms. Some passages are specifically about Christ and not David, for
instance in Psalm 16:10 "For thou wilt not leave my soul in hell;
neither wilt thou suffer thine Holy One to see corruption". (But some
passages seem to be only about David and not Christ, eg. Psalm 40:12
"mine iniquities have taken hold upon me, so that I am not able to
look up." Even the ordering/numbering of the Psalms seem to be
supernatural if you consider the mirror pattern to be valid. I also
see that at least certain Psalms seem to echo strongly other Biblibal
passages, even those Biblical books written after David's time. For
instance, Psalm 103 and 107 remind me of Isaiah 40-47. Psalm 30
reminds me of the Book of Esther. Years ago, I wrote about how Psalm
121-129 seem to be correlated to Revelation 12:1-9.

I think there is a lot for us to discover, reflect upon and chew
through. God Bless you on this journey!
