Wealth brings many friends, but a poor man’s friend deserts him.
~ Proverbs 19:4
As men, so many of our “friendships” are based around the people at your workplace, and work comes down to one thing – money. The need for it and ways to get more of it. I would bet that the majority of the guys you consider friends are connected to work.
Think through all of your peer circles and the men you call "friends". How many of them would stick around if you lost your job? How many would stay connected if you changed your vocation and location?
Work friends are great! However, make sure you spend time cultivating connections which will stick with you no matter the job. The kind of men who will pray with you, help carry your problems, and allow you into thier secrets.
Don't wait on others to approach you when God moves your spirit - reach out to your brothers and build those bridges and friendships.
