'God's purpose for us is to show, as we get older, that he gives us his strength and, through our experiences of him, his wisdom,' says Ian Knox. 'God is not finished with us. In our later years we are not only to be blessed, but to be a blessing and bring a blessing.'

As we get older, some of us grow more frenetic in our anxiety to demonstrate that the force is still with us. Others withdraw, often quite abruptly.

What is God's view of ageing? The Bible has much to say, and many stories to tell, about those who did great things, those who did ordinary things well, those who prayed, those who used their gifts, those who suffered, those who went right to the end – and those who, in later years, got it absolutely wrong.

How are we going to face the prospect of ageing? Will we subside, give up? Or shall we view retirement as a gift from God, an opportunity to reach out to others? Our older years are full of possibilities, not least of which is that of helping others find Christ.
