Friendship is central to Christianity.
This includes listening to them when they talk, congratulating them for their achievements, and making them feel that their company is wanted when they are around.
Being a good friend is of great value to others, Christian or non-Christian, and it should be a focus of the Christian life. Unfortunately, many people from an early age experience many friendships where they don't feel treated that well. This is why when it comes to friendship, there is a definite gap in many people's lives for Christians to fill.
From a young age, people can experience friendships where their friends seem like friends one day and then seem unlike friends another day. People can also often feel that their friends don't really respect them or that they are only hanging out with them until they find someone they like more. Many people can also often feel the humor their friends direct toward them usually goes too far in the wrong direction.
However, Christians, who emphasize empathy in how they interact with others, should focus on treating friends with respect and showing them that their presence is valued. This includes listening to them when they talk, congratulating them for their achievements, and making them feel that their company is wanted when they are around. As an exception to this approach, it is important to keep in mind that some people who seem like they need a good friend, including other Christians, may still not always appreciate the respect of a friend for different reasons, and if a relationship with someone doesn't seem healthy because of how they return disrespect for respect on a regular basis, that can be a legitimate reason to part ways.
