I have had troubles, have felt pain, exhaustion, sorrow, and hopelesness. But this verse tells me that God has used this to comfort me, therefore giving me a heart to comfort those who are going through the same thing by sharing God’s comfort I received.

2 Corinthians 1

…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.
