Throughout the Psalms we read admonitions to praise the Lord, to sing songs unto the Lord, and exalt the name of the Lord.  Ultimately, the purpose of human existence is for fellowship with God.  God longs for an intimate relationship with mankind, and worship is one of the vehicles God has designed to promote that intimacy.  The role of the worship leader is twofold:  he/she must be prepared to enter the presence of God, while leading others to do the same.  Unfortunately, many see the role of the worship leader or praise and worship team as performers on the stage–there to entertain the audience.  This could not be farther from the truth.  Praise and Worship should be interactive and inclusive– the praise leaders and the congregation should join together in worship, entering and enjoying the presence of our Lord.
