How can we describe God? We are given many names for God in scripture that describe to us who He is. I AM. I cannot recall any scripture describing Him as Joy but it is the fruit of the Spirit and so I conclude that He is Joy as much as He is Love!
Joy unspeakable is Our God and Lord Jesus Christ dwelling in us, living life fully with us. We cannot explain our joy in Him. It is unspeakable.
His Joy may not be said in words, but it will be seen on our countenance and in our living life to the fullest serving with happiness.
God of Joy, fill us with You till our hearts are so full that we have no words to speak the pleasure that You are to us! Let it shine through us and be a light in the dark world.
