2 Corinthians 1:3-4

Praise be to the God and Father of our Lord Jesus Christ, the Father of compassion and the God of all comfort, who comforts us in all our troubles, so that we can comfort those in any trouble with the comfort we ourselves have received from God.

Praise be to the God and Father of our Lord Jesus Christ
Ephesians 1:3 Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ.
1 Peter 1:3-5 Praise be to the God and Father of our Lord Jesus Christ! In his great mercy he has given us new birth into a living hope through the resurrection of Jesus Christ from the dead, and into an inheritance that can never perish, spoil or fade--kept in heaven for you, who through faith are shielded by God's power until the coming of the salvation that is ready to be revealed in the last time.

who comforts us
Isaiah 49:13 Shout for joy, O heavens; rejoice, O earth; burst into song, O mountains! For the LORD comforts his people and will have compassion on his afflicted ones.
Isaiah 51:12 "I, even I, am he who comforts you. Who are you that you fear mortal men, the sons of men, who are but grass, ..."
Isaiah 66:13 "As a mother comforts her child, so will I comfort you; and you will be comforted over Jerusalem."
2 Corinthians 7:6-7 But God, who comforts the downcast, comforted us by the coming of Titus, and not only by his coming but also by the comfort you had given him. He told us about your longing for me, your deep sorrow, your ardent concern for me, so that my joy was greater than ever.
2 Corinthians 7:13 By all this we are encouraged. In addition to our own encouragement, we were especially delighted to see how happy Titus was, because his spirit has been refreshed by all of you.
