It is Never too Late.

I read a true story recently where a man went to take communion at his church  and afterwards said to his wife. "Everything I have done is worthless." He died of a heart attack two days later. He was an author of novels, screenplays and short stories. He was well known, rich and admired. But I think the Spirit of God spoke to him at church that day. I think this man saw his life as it truly was in the eyes of heaven. 

What he said brought Solomon to my mind. He had tried everything, tasted everything, experienced everything and yet...
"Yet when I surveyed all that my hands had done and what I had toiled to achieve, everything was meaningless, a chasing after the wind; nothing was gained under the sun." Ecclesiasties 2:11

The author's wife said later that he was in the middle of writing a novel and had told her what the last words would be, "...I believe in God."

I don't think we need to despair if we look back on our lives and find we have wasted most of it or done nothing worthwhile. Of course it would be better if we had done some good, but it shows the mercy and loving kindness of God that he will accept us just as we are at each step of our life.

Paul says in 1 Corinthians 3:11-15

"For no one can lay any foundation other than the one already laid, which is Jesus Christ. Anyone who builds on that foundation may use a variety of materials--gold, silver, jewels, wood, hay, or straw. his work will be shown for what it is, because the Day will bring it to light. It will be revealed with fire, and the fire will test the quality of each man's work.

If what he has built survives, he will receive his reward. But if the work is burned up, the builder will suffer great loss. The builder will be saved, but like someone barely escaping through a wall of flames."
