What we choose to know is different from what we actually know. There may be a deliberate ignoring of things that are unwelcome, uncomfortable, or inconvenient.
All of this is inconsistent with mercy, but of course the greatest expression of mercy is the gospel, and those who should arouse our greatest pity are the poor in spirit. What wonderful riches the one who belongs to Christ has to dispense. There are no limits to these resources. The gospel is powerful to help those who are in the utmost misery and to lift up the dead from the grace to life everlasting. But we must see that it is the only cure of souls; we must be ready to speak it in the darkest corners of the earth. Callousness in this case leaves a lost soul with no hope for ever. Through cowardice, indifference, laziness, shame, we will not speak when the small part that we are called to play is able to bring disproportionate blessing if only we would stir ourselves.
