The wise Christian will first decide what he wants to be like. Then he will associate himself with that crowd.
If you want to be a critical person, do it on purpose. Find the critical crowd and run with them. You will be successful in your goal.
If you want to be a weak Christian, do it on purpose. Find the weak Christians and run with them. Likewise, if you want to be a strong Christian, do it on purpose. Find the strong Christians and run with them.
Once you have decided what you want to be and have found the crowd that can influence you to be that, get with that crowd and relax!
