When people see this—our love for one another and our unity through love—then they will in turn be drawn by this to Christ and will respond to the gospel’s offer of salvation. More often than not, it is what you are rather than what you say that will bring an unbeliever to Christ. This, then, is the ultimate apologetic. For the ultimate apologetic is: your life.
