James Boice writes: “The only way anyone will ever be saved is if God operates entirely apart from us and for his own good pleasure” (The Gospel According to Matthew, vol. 2, p. 410). We are tempted to look at our own efforts for our salvation and to believe that all “good people” will be saved, no matter their religious affiliation. It is therefore vital to constantly remind ourselves that none of us would love and serve God apart from His grace.
