A good look at love would be a picture of God and Jesus in Heaven. We can visualize such an ideal in that God gave the world Jesus. The question is: What did the world do with such a gift?
We can express joy in numerous ways. Jove is a gift from God. This gift was given out of love because God is love. However, the world killed Jesus for all of the wrong reasons. The world is and can be a cruel place.
God is love. We can see God's love in Christ Jesus. He gave His life to save us from a world lost in sin. This is love at its best. Jesus is the love of God, and this is the joy of the Lord.
