Ed Ferner "In the Scriptures, the two ages are contrasted against each other. "This age" is contrasted with "the age to come." In order to read and understand the Scriptures it is imperative to have a grasp of the use of these expressions and what they mean. An initial examination of these two phrases should lead to the following conclusions. The phrase "age to come" implies that the age spoken of has not yet come and is distinct from whatever the present age entails. It also makes a statement that whatever the "this age" represents, it requires that "this age" has to have an ending to it. Since the "age to come" nowhere in the Scriptures is said to have an end, then the phrase "the last days" in the Scriptures must apply to the end of the "this age" time period or the Old Covenant. The end of the "this age" (Old Covenant) time period then becomes the time when God's eschatological program of events would be fulfilled.
"This present age" is the Old Covenant and ended theologically at the cross and was completed in actuality at the destruction of Jerusalem in AD 70. "The age to come," although spoken of as a future event in the Scriptures, was the replacement of the Old Covenant with the New Covenant. This is no longer a "future event" but a present reality in the life of the Christian today, having taken place at the cross and consummated in AD 70."
