1. Susanna Wesley borne nineteen children, including John and Charles Wesley. One day John asked her to define sin. The following is her definition of sin: "Son, 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 power of the flesh over the Spirit, then that to you becomes sin, however good it is in itself." 2. I don't know if John Wesley (would later become a theologian himself) got all of that, but Mrs Wesley was some theologian.
