Jesus is not after any old joy for you. The kind of joy Jesus wants you to possess is His kind of joy. ‘These things I have spoken to you, that my joy may be in you.’ What kind of joy is Jesus joy? From the context I take it to mean the joy Jesus has in abiding in His Father’s love and in obeying His Father’s commands.
This means the kind of joy Jesus wants you to experience is the joy of abiding in His love, and of obeying His commandments. As we saw from the previous devotion, this kind of joy happens when we love one another.
There is a certain paradox here. From one perspective, loving one another entails the denial of joy. Love is always costly, requiring your time, energy, and money etc. These are things that could be used to further the pursuit of your own personal pleasures. So in one sense the command to love can seem like a threat to happiness. But these words from Jesus help us realize that when Jesus commands us to love one another, He doesn’t have the lessening of our joy in mind. He is really calling us to exchange the pursuit of inferior pleasures for that of superior ones. ‘These things I have spoken to you, that my joy may be in you, and that your joy may be full.’
