Have friends, be friendly! God is interested in every aspect of your life. He desires the very best for you. He sent Jesus to the cross on your behalf so that you might have life and have it more abundantly (John 10:10). Jesus is the friend that sticks closer than a brother. He has promised to never leave you nor forsake you.
The Bible says that in order for you to have friends, you must be friendly (Proverbs 18:24). Your environment and the way you live your life will have a lot to do with the type of friends you will have. The most important thing you need to look for in a friend is that they have a desire and love for the things of the Lord as you do.
You do not have to continue to fellowship with someone who conducts themselves as the world does. This does not mean that you stop loving these people or acknowledging them. You simply do not have to maintain a close relationship with them (2 Thessalonians 3:11-15).
As you seek first the kingdom of God and His righteousness, all of these things (desires of your heart) will be added unto you. In the meantime, enjoy your life serving your heavenly Father. Do not allow Satan to rob you of your joy and fellowship with God.
We agree with you that you have the wisdom of God in choosing your friends.
