With a smile I reply that, sadly, that is probably true. The reason is that, whereas the Lord Jesus can see into people’s hearts and so know for certain who is really his, we mere mortals can’t. So, persuaded that we should be aiming at a church membership made up of real Christians, the leadership listens to people’s stories of how they came to Christ and looks for signs of genuine godliness and obedience to Christ and his commands. Obviously, we can’t guarantee we always get it right, but, with God’s help, we do our best.
