How do we know that God desires us to rejoice always?

In 1 Thessalonians 5:16-18, the Apostle Paul explicitly states that rejoicing, praying without ceasing, and giving thanks in all circumstances are the will of God for His people. The command to rejoice evermore indicates that joy is not dependent on our circumstances but stems from our relationship with Christ. This joy reflects our trust in God's sovereignty and goodness. Paul encourages believers to remember the blessings of salvation and the love of God, which should inspire continual rejoicing regardless of life's trials. Thus, the biblical exhortation to rejoice continually is a vital aspect of living a faithful Christian life.
