The Apostle Paul closes his first letter to the Thessalonian church prioritizing the two values of fellowship (5:11-15) and worship (5:16-22). We enter into the section of corporate worship this Sunday morning with a focus that we are to be rejoicing in our worship (5:16). Even though the church at Thessalonica faced afflictions, sufferings, and tribulations, they were to always rejoice! This is not a natural, human happiness but a supernatural, Holy Spirit joy. This rejoicing is placed in our great and glorious God. This joy springs out of the truth of God’s Word. We have a deep-down confidence that God is in control, that He is the only wise God, and that He loves us with an everlasting love. This is the basis of true and genuine joy and why we trust Him with our whole heart. This flows from our appreciation of God’s character, the treasure of Jesus Christ, and the ministries of the Holy Spirit. Our worship of our God is full of joy and rejoicing for the glory of God.
