Psalm 90:1-2
Lord, thou hast been our dwelling place in all generations. Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God.

God has moved in the past, God is moving in the present, and we will see Him continue to move in the future. There has been a passing from one generation to another of the precious Gospel of Jesus Christ. And there's a real ministry when someone from an elder generation is able to pass on, pour into, and disciple a younger generation. There's something special about that in the Lord, and if you don't have that, you need that. 

If the Lord tarries, we must be that for the generation after us.
