Mission is the result of God’s initiative, rooted in God’s purposes to restore and heal creation. “Mission” means “sending,” and it is the central biblical theme describing the purpose of God’s action in human history. God’s mission began with the call of Israel to receive God’s blessings in order to be a blessing to the nations. God’s mission unfolded in the history of God’s people across the centuries recorded in Scripture, and it reached its revelatory climax in the incarnation of God’s work of salvation in Jesus ministering, crucified, and resurrected. God’s mission continued then in the sending of the Spirit to call forth and empower the church as the witness to God’s good news in Jesus Christ.
