"Traditional" vs. "Contemporary"

But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him. God is a Spirit: and they that worship him must worship him in spirit and in truth.
(John 4:23-24)

"Traditional" worship services run the risk of becoming too comfortable, stale, and even boring; where the mind wanders and the true focus on Christ is lost. "Contemporary" services run the risk of becoming chaotic, noisy, and confused; where the true focus leaves Christ for some emotional experience.

True worship is "in spirit and in truth". All spirit and no truth is apostasy; all truth and no spirit is dead religion. If a church is faithful to teach the Bible and spiritual fruit comes from that church, then it is worshiping "in spirit and in truth" whether it calls its service "traditional" or "contemporary". If a church teaches the latest "best-selling" Christian book (though no book has ever out-sold the Bible), or the pastor teaches without constantly referring to the Bible, or the church discourages the congregation from bringing/reading their own Bibles, then that church is not worshipping in truth. It is almost certainly in apostasy, or quickly headed that way. If a church does not bear fruit (for instance: have a youth ministry where children are brought to a saving faith in Christ, or have an effective evangelism effort in its community, or baptizes new believers monthly, or sends off missionaries or families to establish new churches, ... ) then it is practicing dead religion, it has no spirit.

If either, or both of the above descriptions fit the church you are currently attending, then prayerfully consider what you might do to change the situation. Boldly speak the truth.

Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
(Revelation 3:20)

This was written, not to “sinners” but to a church! There are, unfortunately, many churches in America today, where the Lord Jesus Christ stands outside the door, desiring to be invited in. I believe it is the job of true Christians to open these doors.

And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God; I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot. So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth.
Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked: I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see.
As many as I love, I rebuke and chasten: be zealous therefore, and repent. Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.
He that hath an ear, let him hear what the Spirit saith unto the churches.
(Revelation 3:14-22)
