1 Corinthians 10:31 "Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God."
Our highest goal as believers is to glorify God. In practical terms that means that all of our activities must reflect His character and attributes. There are many movements and ministries which may have good intentions, but seek to minimize doctrine in the name of unity or evangelization. We must kindly disagree and separate ourselves unto a holy God Who demands our holiness.
Ephesians 4:11-13 11 "And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; 12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: 13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ."
The job of the pastor is to equip the people in the pews so that they can do the work of the ministry and fulfill the Great Commission.
Ephesians 5:19 "Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord."
Music in the believer's life must not be focused on what people like, but on what God likes. God-honoring music shouldn't be boring or stale, but neither should it be indistinguishable from the music of the culture around us which is designed to please the flesh.
