We need friends because this life is difficult. We don't know everything so we need to depend on people.
A person can have two types of friends. One type of friends are friends with a fear of the Lord.
These types of friends will encourage people to focus on the Bible and Jesus. They are faithful to their friends.
Then there are the unfaithful friends. They don't want to follow Jesus so they have bad advice for their friends. There is no wisdom from the Bible when they encourage their friends.
I know many people that had bad friends and the friends destroyed the person's life. They had a love of Jesus then it disappeared.
Then I know people that want Jesus and have friend that love Jesus. These type of people will be strong in Jesus.
