There is a kind of cavalier attitude toward our security today. There is little trembling. Little vigilance and earnestness and caution and watchfulness over our souls. There is a kind of casual, slack, careless attitude toward the possibility that we might make shipwreck of our faith and fail to lay hold on eternal life. We have the notion that security is a kind of mechanical, automatic thing. We prayed once to receive Jesus. We are safe and there is no place for 'working out your salvation with fear and trembling' (Philippians 2:12).
