Joy and happiness
If by happiness we understand the unperturbable serenity of someone who is above all the changes in life, we can affirm that Jesus was happy, joyful.
One of His constant themes, when He spoke privately with the disciples, is the joy that filled His heart as a result of the willingness and trust with which He surrendered to His Father’s will.
Do not be afraid, do not let your hearts be troubled, live content and happy for I am going to my beloved Father (Jn 14:28). I want you to share my joy and happiness; just as the Father is always with me and because of this I live happily, I would like you to share that same happiness (in 16:12-24).
Shalom -a type of total blessing- is what He leaves them as their inheritance. “Peace I bequeath to you, my own peace I give you” (In 14:27). He had always lived surrounded by that peace (happiness). Leaving it like the greatest treasure means that His own had seen Him live in that serene joy, and it is given to them as an inheritance, but on condition that they also live in that same state of faith and trusting surrender in the hands of the Father.
Here is the particular greatness of Jesus and of all Christians: the ability to live in the midst of trial and failure with a spirit filled with serenity and calm, the ability to be profoundly happy living in the face of adversity.
This is the most delicious fruit of sensing that God is Father and of living surrendered in His blessed hands.
