As one preacher put it, “If you have moderation in all things, that would mean moderation in sin—that it’s okay to sin as long as you didn’t do too much of it and this cannot be! This saying has nothing to do with the Bible in content or principle!
Instead, Jesus urged the Laodiceans, and us, to be hot or cold (refreshing) and not lukewarm. (Revelation 3:15,16) Our prayers are to be fervent (James 5:16) and persistent (Luke 18:1) and we are to love one another deeply. (1 Peter 4:10)
Jesus was continually behaving in ways that were anything but moderate—healing ALL the sick (Matthew 8:16), and on the Sabbath (Mark 3:2). When he fed the multitudes, he didn’t just feed them a snack but enough to satisfy every one and have a large amount of food left over! (Mark 14:20)
In addition, Paul insisted that there shouldn’t be,“even a hint of sexual immorality, or of any kind of impurity, or of greed,” (Ephesians 5:3)—no moderation there! He further urged that followers of Jesus are to “ have nothing to do with the fruitless deeds of darkness,” (Ephesians 5:8) not even a little bit.
Never be lacking in zeal, but keep your spiritual fervor, serving the Lord. (Romans 12:11)
(Fervor: great warmth of emotion. Zeal: intense enthusiasm. Webster’s New World Dictionary)
