A little leaven leaveneth the whole lump. Galatians 5:9
The apostle here warns of the effects of doctrinal error. Like a little bit of leaven leavens the entire lump of dough, so doctrinal error — even seemingly minor errors — affect the entire body of doctrine. Errors in one article of faith affect all articles of faith.
O God, preserve me from the leaven of false doctrine that I may be preserved in the true and saving faith unto life everlasting. In Jesus’ name, I pray. Amen.
