What brings you joy?  What if you made a list, what would be on it?  Jesus experienced joy.  What things do you think brought Jesus joy?  
Joy is much deeper than happiness.  Joy is not dependent on life’s circumstances.  Joy is an emotion that is an outpouring of being connected with God. 

Luke 10:21-24 NIV
21 At that time Jesus, full of joy through the Holy Spirit, said, “I praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and learned, and revealed them to little children. Yes, Father, for this is what you were pleased to do.
22 “All things have been committed to me by my Father. No one knows who the Son is except the Father, and no one knows who the Father is except the Son and those to whom the Son chooses to reveal him.”
23 Then he turned to his disciples and said privately, “Blessed are the eyes that see what you see. 24 For I tell you that many prophets and kings wanted to see what you see but did not see it, and to hear what you hear but did not hear it.”

 What is the source of Jesus’ Joy in this passage?  

John 15:1-11 New Revised Standard Version (NRSV)
Jesus the True Vine
15 “I am the true vine, and my Father is the vinegrower. He removes every branch in me that bears no fruit. Every branch that bears fruit he prunes[a] to make it bear more fruit. You have already been cleansed by the word that I have spoken to you. Abide in me as I abide in you. Just as the branch cannot bear fruit by itself unless it abides in the vine, neither can you unless you abide in me. I am the vine, you are the branches. Those who abide in me and I in them bear much fruit, because apart from me you can do nothing. Whoever does not abide in me is thrown away like a branch and withers; such branches are gathered, thrown into the fire, and burned. If you abide in me, and my words abide in you, ask for whatever you wish, and it will be done for you. My Father is glorified by this, that you bear much fruit and become[c] my disciples. As the Father has loved me, so I have loved you; abide in my love. 10 If you keep my commandments, you will abide in my love, just as I have kept my Father’s commandments and abide in his love. 11 I have said these things to you so that my joy may be in you, and that your joy may be complete.

Did you notice in this passage, Jesus does not want give us joy, but more specifically His Joy!  The joy that Jesus experiences, he wants to give to us!  How does Jesus’ joy differ from the joy we seek?

Hebrews 12:1-3 New Revised Standard Version (NRSV)
The Example of Jesus
12 Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight and the sin that clings so closely, and let us run with perseverance the race that is set before us, looking to Jesus the pioneer and perfecter of our faith, who for the sake of the joy that was set before him endured the cross, disregarding its shame, and has taken his seat at the right hand of the throne of God.
Consider him who endured such hostility against himself from sinners, so that you may not grow weary or lose heart.

For the sake of Joy, endured the cross.  How can something so painful, so awful, so shameful, bring joy?  If we are Jesus followers, shouldn’t our life be easy and free from pain?  If my life is not easy and free from pain, how can I experience joy in the midst of the pain and difficulties of life?
