How do we know that God is the source of joy?

God, as depicted in the sermon, is not merely joyful; He is 'the source of joy' and 'infinitely joyful.' This concept is rooted in the understanding that God needs nothing outside Himself to be complete or happy. His essence is joy, and as believers, we are called to find our joy in Him. Scriptural passages, such as Psalm 16:11, illustrate that in God's presence, there is 'fullness of joy.' Understanding God as the ultimate source of joy helps believers navigate life's uncertainties and challenges, as joy is not dependent on external circumstances, but rooted in a relationship with the immutable, sovereign, and joyful God.
