Through the Holy Spirit comes our restoration to paradise, our ascension into the kingdom of heaven, our return to the adoption of sons, our liberty to call God our Father, our being made partakers of the grace of Christ, our being called children of light, our sharing in eternal glory, and, in a word, our being brought into a state of all “fullness of blessing,” both in this world and in the world to come, of all the good gifts that are in store for us, by promise, through faith, seeing their reflection as though they were already present, we await the full enjoyment.
Sins against the Holy Spirit and against God are the same; and thus you might learn that in every operation the Spirit is closely conjoined with, and inseparable from, the Father and the Son. God works the differences of operations, and the Lord the diversities of administrations, but all the while the Holy Spirit is present too of His own will, dispensing distribution of the gifts according to each recipient’s readiness
Saint Basil On the Holy Spirit
