Revelation 21:6

And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.

It is done - come to pass. The same Greek as Revelation 16:17. So Vulgate; but A, 'they (these words, Revelation 21:5) are come to pass.' All is as sure as if actually fulfilled; for it rests on God's unchanging word. When the consummation shall be, God shall rejoice over His work, as at the first creation God saw everything that He had made, and behold it was very good. Alpha and Omega. In A B, 'the Alpha ... the Omega' (Revelation 1:8).

Give unto ... athirst ... water of life - (Isaiah 12:3; Isaiah 55:1; John 4:13; John 7:37; Revelation 22:17): added lest any should despair of attaining this exceeding weight of glory. Now we may drink of the stream, then we shall drink at the Fountain.

Freely - `gratuitously;' the same [ doorean (G1432)] as is translated, "(They hated me) without a cause" (John 15:25). As gratuitous as was man's hatred of God, so gratuitous is God's love to man: there was every cause in Christ why man should love, yet man hated Him; there was every cause in man why (humanly speaking) God should hate, yet God loved man. Even in heaven, our drinking at the Fountain shall be God's gratuitous gift.
