Church Purpose Begins At Creation
- Guy Waters argues the church's purpose is woven into creation: to spread knowledge of God through a people who worship and serve him.
- Sin didn't end that project but set the stage for Christ to realize it through the church.
Old Testament Covenants Shape The Church
- Key Old Testament covenants (Abraham, Sinai, David, Jeremiah) progressively organize God's people and point to Christ.
- These stage posts provide signs and institutions that foreshadow New Covenant realities in the church.
Continuity And Discontinuity At Pentecost

- Pentecost brings fuller, wider, and deeper work of the Spirit that expands the people's scope to all nations.
