Joy, the hallmark of Christian life.

Joy is the hallmark of Christian life. Jesus mentions a long list of adverse human circumstances and concludes, ‘rejoice and be glad.’ Each of these adverse circumstances he introduces with the word, blessed.’ Matthew 5:2-12.
The word used for ‘blessed’ can also be translated as ‘happy.’ Some translation have it so. It is the ‘transcendent happiness or religious joy.’ So blessed are those who mourn, blessed are those who are persecuted, and so on ....
We get a sharper picture of the adversities in the parallel passage in Luke 6:20-23.  Luke's version includes poverty, hunger, weeping, being hated, etc... There too Jesus sums it up saying, 'rejoice in that day, and leap for joy, for your reward is great in heaven.'
Followers of Jesus are destined to be happy in all circumstances that their earthly existence throws at them.
The reason for this transcendent joy is that they have a larger vision of life. They can see life that stretches to eternity, beyond this transient earthly existence. The success and failure, joy and sadness, and all the sort of experiences are not final, but there is more to human life. There is eternity or our life that extends beyond the grave to heaven.
Those who have that vision can literally 'leap for joy' now because they can see their reward in heaven. They are not losers at all.
