15 “Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves. 16 You will know them by their fruits. Grapes are not gathered from thorn bushes nor figs from thistles, are they? 17 So every good tree bears good fruit, but the bad tree bears bad fruit. 18 A good tree cannot produce bad fruit, nor can a bad tree produce good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 So then, you will know them by their fruits. Matthew 7:15-20 (NASB)
The fruit of a ministry in God’s economy is not the number of people “converted” under it. No, the fruit, which will be what God will use to judge, refers to the effectiveness that ministry has in leading and developing within those who are ministered to by it unto a Christ-like life produced by the Holy Spirit (Galatians 5:22,23). What is it that those God uses in these ministries do that achieves this? They teach their flock sound doctrine from God’s Word. The Holy Spirit takes these truths and applies them to the hearts of the flock. It is not emotion or feelings. It is being transformed by the renewal of their minds because they are being living sacrifices unto God (Romans 12:1,2).
