All comforts come from God. He comforts us so we can comfort others.
Read: 2 Corinthians 1:3-4
3 All praise to God, the Father of our Lord Jesus Christ. God is our merciful Father and the source of all comfort. 4 He comforts us in all our troubles so that we can comfort others. When they are troubled, we will be able to give them the same comfort God has given us.
