The need is not for more preaching. Congregations are preached at ad infinitum. The church needs deeper teaching. Scriptural preaching is for the salvation of the lost, not the spiritual growth of the believer.
This is what is wrong with the church.
2Ti 4:1 I charge you in the presence of God and of Christ Jesus, who is to judge the living and the dead, and by his appearing and his kingdom:
2Ti 4:2 preach the word; be ready in season and out of season; reprove, rebuke, and exhort, with complete patience and teaching.
People have lost sight of what scriptural preaching is much like in the quote.
