Before we can worship God in peace of conscience and liberty of heart, we must know, on the authority of God’s Word and the power of the Holy Spirit, that the entire question of our sin has been answered for ever by the blood and sacrifice of the Lord Jesus Christ.
We must know that all the claims of God’s holy law and all of our needs as ruined, guilty sinners have been for ever settled in the court of God, by the death of Christ.
This alone gives perfect peace with God; and in the enjoyment of that peace we worship the author of our salvation. Because we have a perfect sacrifice, we have a perfect conscience.
