Making church appealing to our friends and family may be good salesmanship, but it doesn't fulfill the Great Commission. Jesus never told us to sign up young, potentially affluent, wage-earners to fund our building projects. He instead commanded us to make disciples by passing on His doctrine and calling others to obey Him (Matthew 28:16-20). Part of making disciples necessitates helping people acknowledge their sin and move toward repentance.
Such demands repel those people whom the Lord has not called to salvation. But the elect, who mourn over their sin because they know how deeply it offends the Savior, will embrace such preaching as a portal to eternal life. Indeed, Paul and his co-workers observed this very principle, and mentioned it to the church in Corinth:
14 But thanks be to God, who in Christ always leads us in triumphal procession, and through us spreads the fragrance of the knowledge of him everywhere. 15 For we are the aroma of Christ to God among those who are being saved and among those who are perishing, 16 to one a fragrance from death to death, to the other a fragrance from life to life. Who is sufficient for these things? ~~2 Corinthians 2:14-16 (ESV)
Preaching, whether in a church setting or in personal evangelism, can't afford to coddle sin. God's servants don't sell a product; we proclaim the truth--including the fact that the Lord, being perfect in Holiness, cannot and will not tolerate sin among His people. Wondrously, He shed His blood to atone for the sin of those who believe, providing us the grace to live in holiness! May we have the courage to declare the whole gospel, trusting the Holy Spirit with the results.
