Praise be to the God and Father of our Lord Jesus Christ. God is the Father who is full of mercy and all comfort. He comforts us every time we have trouble, so when others have trouble, we can comfort them with the same comfort God gives us.
2 Corinthians 1:3-4 (NCV)
While we have troubles in this world we have peace in Christ. When we receive His mercies and comforts we are able to comfort others and bring glory to Him.
