Aaron and his companions respond to the guidance of the Spirit and are blessed with a harvest of willing souls. Missionaries throughout the world pray for the Spirit to direct them to the honest in heart. Parents plead for the Spirit to help them raise their children in righteousness. Teachers pray with faith so they can teach by the Spirit (see D&C 42:14). We can be assured that the Spirit will lead us to do good, to do justly, to walk humbly, to judge righteously, and enlighten our souls and fill us with joy (see D&C 11:12–13). The Spirit is the key to a righteous life. Are we led by the Holy Spirit?
