Luke 6:21

Blessed are ye that hunger now
Not only suffer hunger and thirst in a literal sense, in this present life, but who have hunger and thirst in a spiritual sense, after righteousness and eternal life, as in ( Matthew 5:6 ) where it is also said as here:

for ye shall be filled:
with righteousness and life; (See Gill on Matthew 5:6).

blessed are ye that weep now;
under afflictions and pressures of life, and mourn for sin, their own, and others:

for ye shall laugh;
be filled with spiritual joy and pleasure, and be comforted with the consolations of the Spirit; (See Gill on Matthew 5:4).
