To meet our responsibility to clean out the old leaven of malice and evil, God provides us Bible tools, Jesus Christ’s words & life, the Holy Spirit, and the community of believers, so we can speak and live in sincerity and truth.
1 Corinthians 5:6-8 (ESV):
6 Your boasting is not good. Do you not know that a little leaven leavens the whole lump? 7 Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. 8 Let us therefore celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth.
