Unbelievers, those who believe with difficulty, or believe in part, are those who do not show their faith through works. Apart from works the demons also believe (cf. Jms. 2:19) and confess Christ to be God and Master. 'We know Who You are' (Mk. 1:24), they say, 'You are the Son of God' (Mt. 8:29), and elsewhere, 'These men are the servants of the Most High God' (Acts 16:17). Yet such faith will not benefit the demons, nor even humans. This faith is of no use, for it is dead.

Symeon the New Theologian

God always was, and always is, and always will be. Or rather, God always Is. For Was and Will be are fragments of our time, and of changeable nature, but He is Eternal Being. And this is the Name that He gives to Himself when giving the Oracle to Moses in the Mount. For in Himself He sums up and contains all Being, having neither beginning in the past nor end in the future; like some great Sea of Being, limitless and unbounded, transcending all conception of time and nature, only adumbrated [intimated] by the mind, and that very dimly and scantily.

Gregory of Nazianzus

Let no one out of laziness or continuous worldly occupations miss these holy Sunday gatherings, which God Himself handed down to us, lest he be justly abandoned by God... If you are detained and do not attend on one occasion, make up for it the next time, bringing yourself to Christ's Church. Otherwise you may remain uncured, suffering from unbelief in your soul because of deeds or words, and failing to approach Christ's surgery to receive... holy healing.

Gregory Palamas

Then there is the further question of what is the relationship of thinking to reality. As careful attention shows, thought itself is in an actual process of movement. That is to say, one can feel a sense of flow in the stream of consciousness not dissimilar to the sense of flow in the movement of matter in general. May not thought itself thus be a part of reality as a whole? But then, what could it mean for one part of reality to 'know' another, and to what extent would this be possible?

David Bohm

It is often said that all the conditions for the first production of a living organism are now present, which could ever have been present. But if (and oh! what a big if!) we could conceive in some warm little pond, with all sorts of ammonia and phosphoric salts, light, heat, electricity, &c., present, that a proteine compound was chemically formed ready to undergo stillmore complex changes, at the present day such matter would be instantly devoured or absorbed, which would not have been the case before living creatures were formed.
