In Deuteronomy 6:5-7 we are reminded that we cannot teach what we don’t know. We are told first, “You shall love the Lord your God with all your heart and with all your soul and with all your might” (5), and then we are instructed to teach God’s Word diligently to our children (7). You cannot teach your children (or friends, or co-workers, or others you have opportunity to disciple) to love what you do not love yourself.
Our goal when speaking to other Christians or unbelievers, Paul reminds us in Ephesians 4:15, is not to “debunk every belief you have.” It is to share the truth in love. The difference in these two ends should therefore lead to very different means, as well.
