How can we be sure that these radiant hopes are better than delusions, lights thrown on the black curtain of the unknown future by the reflection of our own imaginations? Only because He that sitteth on the throne,' and is therefore sovereign over all things, has declared that He will make all things new.' His power and faithful word are the sole guarantees. Therefore seers may write, and we may read, and be sure that when heaven and earth pass away His word shall not only not pass away, but bring the new heavens and the new earth. So sure is the fulfilment, that already, to the divine mind, these things are come to pass.' Faith may share in the divine prerogative of seeing things that are not as though they were, and make the future present. He who is Alpha, the beginning, from whom are all things, is Omega, the end, to whom are all things. There lies the security that the drift of the universe is towards God, its source, and that at last man, who carne from God, will come back to God, and Eden be surpassed by the new Jerusalem.
The conditions of entering the city are gathered up in words which recall many strains of prophecy and promise. Thirst is the condition of drinking of the water of life--as John the Evangelist delights to tell that Jesus said by the well at Samaria and in the temple court. Conflict and victory make His children heirs of these things, as the Christ had spoken by the Spirit to the churches. The Christian victory perfects the paternal and filial relation between God and us. And all three promises are but variations of the answer to the question: How can I become a citizen of that city of God?
