The Bible has much to say about loneliness and the importance of friends. Casual friends can be the result of circumstances, but close friends should be the result of wise choices. Your closest friends will have the most influence on your life, so they should be those who encourage you spiritually, support you emotionally, and challenge you mentally. To have a best friend, you must be a best friend by being considerate and listening well. The secret of making friends is not to be interesting, but to be interested.
