"Because salvation is by grace through faith, I believe that ..." — Brennan Manning quote meaning

Because salvation is by grace through faith, I believe that among the countless number of people standing in front of the throne and in front of the Lamb, dressed in white robes and holding palms in their hands (see Revelation 7:9), I shall see the prostitute from the Kit-Kat Ranch in Carson City, Nevada, who tearfully told me that she could find no other employment to support her two-year-old son. I shall see the woman who had an abortion and is haunted by guilt and remorse but did the best she could faced with grueling alternatives; the businessman besieged with debt who sold his integrity in a series of desperate transactions; the insecure clergyman addicted to being liked, who never challenged his people from the pulpit and longed for unconditional love; the sexually abused teen molested by his father and now selling his body on the street, who, as he falls asleep each night after his last 'trick', whispers the name of the unknown God he learned about in Sunday school.
