I just happen to have the source right here: (The Teachings of Ezra Taft Benson [1988], 104-5)
I quote:
"God has held you in reserve to make your appearance in the final days before the second coming of the Lord. Some individuals will fall away; but the kingdom of God will remain intact to welcome the return of its head--- even Jesus Christ. While our generation will be comparable in wickedness to the days of Noah, when the Lord cleansed the earth by flood, there is a major difference this time. It is God has saved for the final inning some of His strongest children, who will help bear off the kingdom triumphantly...."
also he mentions this:
"... Make no mistake about it-- you are a marked generation. There has never been more expected of the faithful in such a short period of time than there is of us" (The Teachings of Ezra Taft Benson [1988], 104-5)
