"If we are not harder than iron, this exhortation ought to soften us, and render us disposed to forgive offences. Unless God pardon us every day many sins, we know that we are ruined in innumerable ways: and on no other condition does he admit us to pardon, but that we pardon our brethren whatever offences they have committed against us. Those who refuse to forget the injuries which have been done to them, devote themselves willingly and deliberately to destruction, and knowingly prevent God from forgiving them."--John Calvin, Commentary on the Harmony of the Evangelists, Matthew, Mark, and Luke, Vol. 1, 330.
