Friends are like windows through which you see out into the world and back into yourself. If you don't have friends you see much less than you otherwise might.
Life is a test. It is only a test--meaning that's all it is. Nothing more, but nothing less. It is a test of our convictions and priorities, our faith and faithfulness, our patience and resilience, and in the end, our ultimate desires. It is a test to determine if we want to be part of the kingdom of God more than we want anything else.
