Is Christianity for this Life or the Next? (Lk 6:17,20-26)

I have always found an unattractive expression of Christianity is to be good in this life to go to heaven in the next. Christianity's power is it helps now bring strength purpose meaning and many other blessings into our life. However, it is true that the promise of life to come also is a tremendous blessing. We are called to live as agents of transformation in this world never fully succeeding but longing for the completion to come after we die.
