I can still recall the conversation although it took place more than three decades ago. A shocked friend asked, “Have you heard that Sarah is no longer a Christian?” What was so alarming to my friend was that Sarah had been one of the most influential, and apparently fruitful, members of her Inter-Varsity group. What would those who had been influenced by her witness to Christ say, or do? Would they be shaken to the core and now doubt their own Christian faith? After all, the person who had pointed them to Christ no longer trusted Him.
On occasion, we wonder if an individual really has been converted. And sometimes we have an inexplicable, ill-defined sense that something is missing. But we cannot read the heart. Even so, we hear of friends—whose faith we never doubted—turning away from Christ.
Apostasy is the old, vigorous word to describe this abandonment of Christ.
