“Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort; who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God. For as the sufferings of Christ abound in us, so our consolation also aboundeth by Christ. And whether we be afflicted, it is for your consolation and salvation, which is effectual in the enduring of the same sufferings which we also suffer: or whether we be comforted, it is for your consolation and salvation.” 2 Corinthians 1:3-6 (KJV)
In times of sorrow from loss of a family member, a friend, or in times of financial chaos; or some other catastrophic event it is an encouragement to a Christian to know that GOD is the one who comforts us. He is the source of all our comfort.
Of course we need to realize that He comforts us many times through friends, family, neighbors and loved ones. Sometimes though these may fail us; and it is then that God will give us peace and comfort through His Spirit who abides within and through His Word.
Through our own trials and tribulations we learn to console and comfort others.
