"We fulfill God's commandments, then, through his Spirit, who alone knows the Lord's will. And when the Spirit has perfected us in himself and he is perfected in us, and we have been purified from all defilement and stain of sin, he will present us pure and spotless, like fair brides, to Christ. Then we shall rest in God and in his kingdom, and God will rest in us for ever. Glory be to the Lord's compassion, mercy, and love, because he has deigned to bestow such honor and glory on the human race, making them children of the heavenly Father, and calling them his own brothers and sisters."
Macarius of Egypt (4th-5th century), Hom. 19, 6-9: PG 34, 645-649
