Jesus taught: “For no good tree bears bad fruit, nor again does a bad tree bear good fruit; for each tree is known by its own fruit. For figs are not gathered from thorns, nor are grapes picked from a bramble bush.” (Luke 6:43-44)
“…Even though the Church is a unity, it is a unity of distinct personalities. It is an assembly of persons, each one of them whole and complete, standing before God, and not an anonymous, undifferentiated mass. Thus it is entirely possible for all of us to be gathered together in church, to be standing next to each other and chanting in unison, but for each of us to get something different out of the experience. And what each of us receives is known only to that person, only to the spirit of the man, which is in him, as well as to God the Spirit, Who searches the depths of our own spirit (cf. 1 Cor. 2:10-11). What, then, did we receive? In the first place, we received what we prepared ourselves to receive. Whatever food you’ve prepared, that’s what you’ll eat. Whatever bed you’ve made, that’s the one you’re going to lie on. Whatever you’ve sown in your field, that’s what you’ll reap. Throughout the liturgical year, then, we receive what we have prepared ourselves to receive. God will not bring something to fruition that we have not had a hand in cultivating; and what we cultivate, that which we expect to bear fruit, grows directly from the seeds we’ve sown within ourselves.
Consequently, we’ll get whatever it is our heart has prepared for itself. One person will get God; another will be moved by the chanting; another will gain a few insights; someone else the kingdom of heaven. Each will receive whatever it is he desired.[…]What we find depends on the way we seek for it. The way we see God, in other words, determines what we shall see in God. This is what I say: what you’ve prepared yourself is exactly what you’ll receive. One person cultivates the wind, and reaps nothings. Another prepares to receive the Holy Spirit. It all depends.” (Archimandrite Aimilianos, The Way of the Spirit, pp 129-130)
