It would be easy to say it is a temporal happiness, a feeling one experiences. But then what about the trying times of life? The misery and sufferings that are around us. How about those of us who suffer from depression (I'm one of those)?
It reminds me a little bit about how when one looks at the Beatitudes Jesus says, "Blessed are the poor...", "Blessed are the hungry..." etc. Some translations render "Happy are the poor...".
Well what do we mean by "happy"? The word "makar" (prolonged as the adjective
makarios in the Beatitudes) speaks of contentment, fulfillment, one who has their fill, their fullness, needing nothing else. Thus blessed are the poor, blessed are the hungry, blessed are those who mourn, blessed are those who suffer, etc becomes obviously a strange thing to say.
It's obviously not a happiness we are well acquainted with. If I am starving and in need of food, am I truly happy? Not really, but the beatitude says I am, against all odds and what I see and experience right not, one who has everything already. How so? Presumably it comes with the promises attached to the Beatitudes, "for yours is the kingdom of God", "for you shall be filled", "for you shall be comforted" etc.
The blessedness, the contentment, the happiness is in the God who in justice restores all wrongs to rights.
What is the joy of the Spirit? Is it this fleeting, temporal happy feeling? Or is it the joy of the knowledge that being baptized I belong to Christ, and if I am Christ's, I am God's. And if I am God's, I have more than I could ever hope for in this life, and so even in misery there is joy, not that I feel happy when I am miserable, but that in faith I know the misery of this life cannot rob from me the goodness and kindness of God and what He has promised me in Jesus.
It is a terrible thing when certain Christians promise a rose-petal road of happiness and good things in this life. Because unless you are one of the most fortunate with many material things, without material worries, etc for the majority of us--all of us--this life is a cross that we carry every day. And even for the most fortunate, they are not blind to the suffering around them, and are not immune to disease, or the changing tides of society and economy.
That isn't to say everything in this life is horrible blech, it's to understand that in the real world there is suffering, and the Christian ethos is to know that suffering, and know it as a cross to be carried, and through that love and do good to our neighbor. Because the burden of the cross in this life is not the final word about human existence, there is an empty tomb near Calvary that preaches to us that cross and death are not final, are not what ultimately defines the world, or ourselves, but that Jesus Christ risen from the dead is God's final word to all creation.
