Here is an interesting book excerpt: If you make a few assumptions about the mixing of gases and the lifetimes of molecules in the atmosphere, it turns out that, on average, one molecule of “Caesar air” — or any other historic liter of air, for that matter — appears in each breath you take. (Caesar’s Last Breath by Sam Kean)
So in every breath we take we may take in a molecule of air that Jesus breathed. It turns out that He is not only (though more importantly) with us in His Spirit – but physically he is still with us too. That makes me breathe more consciously and deeply and spiritually, knowing that he will be with me until my final breath. BREATHE!
