Always rejoice, incessantly pray and thank God for everything, - says Paul.
Some may wonder if it is possible to fulfill this. Rejoice? Yes. But surely not always. Pray? Yes, but not incessantly, of course. Thank God? Certainly, but not for everything, to be honest.
But if a person manages to embrace with all of his or her heart the idea of all material things, irrespective of essence and forms, being invariably filled with the divine light, - invisible, yet real and feeding his/her soul with life, then wherever this person may be, whatever may be happening to him/her, no matter what thing his/her eyes may see at the moment, there is always a good reason to rejoice and thank God for literally every and any thing, which, in its turn, entails an incessant praying.
Yet, of course, it is easier said than done. Personal psychology, personal preferences and loathing, personal likings and disliking step in with their protests though they usually remain quite passive when the talk is about invisible atoms, not about the invisible light of God's grace, equally filling all things.
