You’re saying that preaching doctrine leads to spiritual growth. Actually, I would say that preaching doctrine can lead to spiritual growth. But I think it’s a big mistake to assume that people will necessarily love and follow Jesus just because we preach sound doctrine. People’s hearts have to be touched. As I like to say, there’s a big difference between knowing that honey is sweet because you’ve read about honey in a book and experiencing the sweetness of honey by tasting it for yourself. The Devil has sound doctrine, and it hasn’t done him any good. We should help our congregations taste the sweetness of God. That’s when transformation happens.
Actually, I favor both knowing about the honey and tasting it! Truth and experience: What God has joined together, let not man put asunder!
