2 Corinthians 1:4; 2 Corinthians 1:6

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.
6 Even when we are weighed down with troubles, it is for your comfort and salvation! For when we ourselves are comforted, we will certainly comfort you. Then you can patiently endure the same things we suffer.
