Reading John Piper’s ‘Future Grace’ now – a classic indeed, and I’m only on chapter 2! Piper touched on a thought that he did not deliberate on as he was making another point, but…

Think about this: of all the things that we give to God, from the sacrifices called for in the Old Testament Law (out of things owned) to our time and talents today, there is nothing that can really be given to God, since all things in heaven and earth belong to him; were made by him in the first place. All things, except one!: our thanks! This is the only thing we can give freely that he will not make us give, so of all that we have, this is the greatest sacrifice we can give and the most precious thing he desires: our worship.

Is this biblical? Too right! In Psalm 50:12-14, God admonishes us –

If I were hungry I would not tell you,
for the world is mine, and all that is in it.
 Do I eat the flesh of bulls
or drink the blood of goats?
