Psalm 145, stanzas 1 – 4 teaches that worship is contagious and when spiritually infected people worship, the consequences are not just transformational but generational.  In these stanzas, the author's experience of worship moves from the individual to the community, from the personal to the public, from the one to the many and from isolation to integration. This sermon focuses on the motivation, mechanics, measure and ministry of "contagious worship" as the key components of that movement.
