Charles Finney addresses the sin of injustice to character, emphasizing that we must not judge others based on isolated actions but rather on the overall state of their character. He warns against the dangers of prejudice, selfishness, and the absence of love, which lead to unjust judgments. Finney highlights that character is revealed through habitual actions and intentions, and that forming opinions without sufficient knowledge is a grave error. He stresses the importance of mutual love and consideration in all relationships, urging believers to avoid the sin of slander and to uphold the dignity of others. Ultimately, he calls for self-examination and repentance for those who have wronged others through unjust judgments.
