How should believers respond to deliverance- Psalm 66 looks forward to the opening portion of morning public worship on the coming Lord's Day. In these twenty verses of Holy Scripture, the Holy Spirit teaches us that when a believer realizes that his deliverance from trouble is fruit of deliverance from sin and part of God's mighty, redemptive work of a multitude from all the nations, he wishes for all the redeemed to join him in praising God in public worship.
