The recovery of spiritual sight and the healing of physical blindness have much in common. Some of those whose bodily eyes were blind received their sight at once, like the man who heard and immediately saw and was healed. Others recovered their sight gradually as in the case of the man, who, before he was completely cured, said, โI see men as trees, walkingโ. It is the same with those whose spiritual eyes were healed.
Gregory PalamasIf you put something fragrant on to burning coals, you motivate those who approach to come back again and to stay near, but if instead you put on something with an unpleasant, oppressive smell, you repel them and drive them away. It is the same with the mind. If your attention is occupied with what is holy, you make yourself worthy of being visited by God, since this is the sweet savour which God catches scent of. On the other hand, if you nurture evil, foul and earthly thoughts within you, you remove yourself from God's supervision and unfortunately make yourself worthy of His aversion.
Gregory Palamas...the grace of the Spirit takes possession of the quiet soul, and gives it a taste of the unspeakable good things to come, which no passionate and negligent eye has seen, nor ear heard, neither have entered into the heart of such a man (cf. I Cor. 2:9). This taste is the earnest of these good things, and the heart which accepts these pledges becomes spiritual and receives assurance of its salvation.
Gregory Palamas'Now we are the sons of God'. This is the starting point of adoption. However, 'it does not yet appear what we shall be: but we know that, when He shall appear, we shall be like Him; for we shall see Him as He is' (I Jn. 3:2). This is the perfection of adoption of sons and renewal which God bestowed on us in Christ, and of which John says in his Gospel that, 'Christ gave power to become the sons of God, even to them that believe on His name: which were born, not of blood, nor of the will of the flesh nor of the will of man, but of God' (Jn. 1:12-13).
