I heard about lamentation worship. What is this? Where is it found in the Bible?
The Bible does not talk about lamentation worship. It is not a biblical concept. That is, it cannot be found in the Bible. If some church or organization is engaged in something called lamentation worship, then they must be contacted to understand what they mean by that term. Lamentation worship could refer to a mourning over one’s sin and be followed by praise of God for His forgiveness. Even though the term does not occur in the Bible, one would have to understand how it is being used in order to determine if it is unbiblical.
Ultimately, all worship should conform to the standard that Jesus established in the following verse,
God is spirit, and those who worship Him must worship in spirit and truth. (NASB) John 4:24
True worship gives honor to God and to God alone. Worship must exalt Jesus Christ as God and Savior and not human effort, accomplishments, or any person. On Sunday morning, worship includes more than singing. It also includes the preaching of God’s Word and prayer.
