But I am like an olive tree
flourishing in the house of God;
I trust in God’s unfailing love
for ever and ever.
(Psalm 52:8)

Or at least, we should be flourishing.  We often find ourselves forgetting that God's unfailing love is just that, unfailing.  I think it's hard for us to absorb this kind of love because our own love is only unfailing in certain circumstances with certain people.  We know that we can't compare any of our own attributes with God's attributes, but I think we do anyway.... after all we're only human.  Leave the reasoning behind and focus on the promises of God which are rock-solid.  Believe, trust, and relax in God's love.
