He is not just everywhere, but also above all, not just in every age and time, but before them all. And, according to the promise, the Holy Spirit will not just be with us until the end of the age, but rather will stay with those who are worthy in the age to come, making them immortal and filling their bodies as well with eternal glory, as the Lord indicated by telling His disciples, “I will pray the Father, and he shall give you another Comforter, that he may abide with you forever.” (John 14:16)
–Saint Gregory Palamas (1296-1359)
