Matthew 5:4 'Blessed are they that mourn: for they shall be comforted.'
To mourn is to feel or express sorrow or grief. The mourning that is addressed in our verse of focus, has to do with mourning or sorrowing over our sins. Mourning over the loss of fellowship and friendship with the Lord. A brief examination of our lives will reveal that we have committed, or are involved in many actions that are contrary to the principles of God. Such a revelation ought to sadden us, for it brings into sharp focus, the fact that our fellowship with God is hampered.
Matthew 5:4 gives us a solution to our mourning- we shall be comforted. When we genuinely acknowledge our sins to God, we are comforted.
The comfort is realized in God’s desire to forgive us. God’s forgiveness provides comfort.
Spiritual comfort enables us to experience the peace, contentment, and satisfaction, that comes with knowing God. Jesus, with His own blood at Calvary, has fully satisfied; completely paid for all our sins. We do not have to live without spiritual comfort. We can confess our sins; receive God's forgiveness and live comfortably in Christ.
