One purpose for older Christians is to train the church to honor and fear God.

Throughout the Bible, the role of older men and women of faith, both in Israel and the Church, was essential to the community’s understanding and rootedness in God. Older saints were not merely purveyors of good advice because they had been around the block more than once, they were the ones who trained the community how to enter the presence of God.

Listen to Leviticus 19:32, “You shall rise up before the grayheaded, and honor the face of an aged, and you shall revere your God: I am the Lord.” Our posture in the presence of age is connected with our honor of God’s nature.

Customs of respect and deference to older people are rooted in God and the fear of God. And the loss of these manners of respect from baby-boomers and teenagers is directly related to their small view of God and the contemporary foreignness of the idea of the fear of God. If God has become a buddy, you can hardly expect people to stand when an old man enters the room.
John Piper, Pastor of Bethlehem Baptist Church

I see this as a major category for older adults in the church, what are other ways that God uses “grey hair” for His purpose?
