How do we know Jesus is the source of true joy?

The sermon points out that Jesus is described as 'the bienaventurado and only sovereign' in 1 Timothy 6:15, indicating that He embodies perfect joy and happiness. While all humans fall short of the law, Jesus fulfilled it completely, having His delight in God's commandments, as referenced in Psalm 40:8. This perfection makes Him the true source of joy for believers, who find their identity and joy in Him. Thus, our joy is rooted not in circumstances but in knowing Christ and the salvation He provides.
