What does the Bible say about being of good cheer?

In Matthew 14:27, Jesus tells His disciples, 'Be of good cheer; it is I; be not afraid.' This phrase signifies not just a call to comfort, but a profound assurance rooted in the identity of Christ as the sovereign Lord over all circumstances. Throughout Scripture, this theme recurs, reminding us that our basis for cheerfulness is found in Christ's power, His conquering of sin, and His ongoing intercession for us. In times of trial and tribulation, believers are called to remember His promises and the certainty of our salvation, which provides a steadfast source of joy and hope.
