As a boy, John Wesley had been thinking about sin and asked his mother, Susanna Wesley, for a definition. Susanna Wesley’s reply, one of such great wisdom and insight both serves to challenge me to always be ready to give an answer but also think more deeply about sin and it’s relation to Christians. Just imagine giving this answer at the spur of the moment to a child.
Whatever weakens your reasoning, impairs the tenderness of your conscience, obscures your sense of God, or takes away your relish for spiritual things, in short, if anything increases the authority and the power of the flesh over the spirit that to you becomes sin however good it is in itself.
