45:17 world without end. This remarkable phrase, “world without end,” essentially means “eternally.” It is one word in the Hebrew, olam, which is also used in Isaiah 64:4, where it is translated “the beginning of the world,” yet still with the basic meaning of “eternally.” Thus these two verses assure us that from “past eternity” to “future eternity” we have the sure promises of God. Therefore, “unto Him be glory in the church by Christ Jesus throughout all ages, world without end. Amen” (Ephesians 3:21).
