What Is 'Praise and Worship' Really?

Through Jesus, then, let us keep offering to God our own sacrifice, the praise of lips that confess His name without ceasing. 
Hebrews 13:15 The Voice Bible

Blackaby writes, "Genuine worship...originates within our hearts." In the Old Testament, under the original covenant, sacrifices hold an important role in the offerings, and Levite priests offer the sacrifices in the temple "on behalf of the people". Blackaby refers to the Levites as "worship leaders of their day." In the New Testament, animal sacrifices lose their importance because Christ become the last blood sacrifice needed, and God clearly emphasizes our praises and thanksgiving in worship. All this makes me think of those we call Worship Leaders in churches today. They are usually the ones who help us give voice to our heart's praises to God.

Music, in its various forms, is central to the worship experience and frequently sets the mood and tone. Through music, the rhythm of our soul's offering of praise to the Lord finds expression. Words cause the mind to ponder His character, expose the soul's deepest need, and provide the heart an opportunity to reply. Matthew Henry, Bible commentator, reminds us that "Christ is both our Altar and our Sacrifice." As we worship, this ceaseless sacrifice of praise defines the authenticity of the Christian heart.

Typically, especially in more contemporary settings, the Worship Leader designs spiritual opportunities and engages the people in what is often referred to as 'praise music'. Comparing Worship Leaders of the OT, with today's Worship Leaders, I find stark contrasts. No longer are animal sacrifices offered for people's sins; today, people directly worship God and stand in His presence because of Grace. Today's sacrifices look different. No more blood sacrifices are needed. Our sacrifice of praise rises to the Lord in prayer and thanksgiving, with song or in Scripture, on chords or in chants, with drums or dance. Worship Leaders exalt God's majesty, while allowing us to examine our hearts and evolve our praise language. Praise and Worship is language pleasing to God!
