How important should a holy life be for a Christian? In this sermon, David Capoccia looks at the teaching of the Apostle John in the letter of 1 John. David Capoccia explains that, in contrast to false teaching circulating during John’s time, Christ’s apostle taught: 1.) Believers must walk in light because God is light, 2.) Believers have been cleansed by and continually seek cleansing in God’s light, and 3.) Believers are empowered to keep God’s law of love by the new light of Christ.
