6. It is done--the same Greek as in Re 16:17. "It is come to pass." So Vulgate reads with English Version. But A reads, "They ('these words,' Re 21:5) are come to pass." All is as sure as if it actually had been fulfilled for it rests on the word of the unchanging God. When the consummation shall be, God shall rejoice over the work of His own hands, as at the completion of the first creation God saw everything that He had made, and behold it was very good (Ge 1:31).
      Alpha . . . Omega--Greek in A and B, "the Alpha . . . the Omega" (Re 1:18).
      give unto . . . athirst . . . water of life-- (Re 22:17; Isa 12:3; 55:1; Joh 4:13, 14; 7:37, 38). This is added lest any should despair of attaining to this exceeding weight of glory. In our present state we may drink of the stream, then we shall drink at the Fountain.
      freely--Greek, "gratuitously": the same Greek as is translated, "(They hated Me) without a cause," Joh 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 Him, yet man hated Him; there was every cause in man why (humanly speaking) God should have hated man, yet God loved man: the very reverse of what might be expected took place in both cases. Even in heaven our drinking at the Fountain shall be God's gratuitous gift.
