“Blessed are those who mourn, for they shall be comforted.”
“Blessed are those who mourn,
This mourning has to do with mourning over sin and not over a loss of a person or object. This is mourning over loss of fellowship with the Lord. The word for “mourn” is the strongest word in the Greek for mourning. It is the word used for mourning for the dead.
Mourning here is not self-pity. We do not use pity for self as the instrument of forgiveness. Our forgiveness comes from the One who died on the cross for our sins. That is why there is blessedness in conviction over sin.
“Blessed” emphasizes God’s part in forgiveness. Our comfort does not rest in who we are or even in the act of mourning but in God’s provision. God provides for us in grace. God frees us from the penalty of sin through the death of Christ on the cross. There remains no barrier between God and man. God forgives us because of who Jesus is and what He did on the cross. He does not forgive us because of the sincerity or intensity of our mourning.
for they shall be comforted.
The comfort here has to do with forgiveness. God directly comforts His people by forgiving their sin.
In the immediate context, all mourning will cease when the King sets up His kingdom because He will pardon the sins of Israel.
Comfort, comfort my people, says your God. Speak tenderly to Jerusalem, and cry to her that her warfare is ended, that her iniquity is pardoned, that she has received from the Lord’s hand double for all her sins. Is 40:1-2
Those who mourn sense their personal bankruptcy and utilize God’s forgiveness.
Spiritual poverty comes from conviction of personal sin. Those who seek close fellowship with the Lord mourn over their sin by seeing sin the way God sees it. They sense their spiritual poverty and unworthiness before God. Note how David viewed his adultery with Bathsheba.
The sacrifices of God are a broken spirit; a broken and contrite heart, O God, you will not despise. Ps 51:17
God blesses us because we have His forgiveness by the death of Christ for our sins.
In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace… Eph 1:7
