Matthew 5:4

Blessed (forgiven, refreshed by God’s grace) are those who mourn (over their sins and repent), for they will be comforted (when the burden of sin is lifted).

The unrecognized sins in our lives will stunt our spiritual growth and lead us away from God.  When we repent, mourn, and recognized that we had come short of God’s best, then we will set be set free.  We can obtain the comfort we want from God when we restore our fellowship.
