By being around people who share a common faith will encourage you and them. Show Him you care about serving Him. Believe it and live it. Get to know the people. See people as an opportunity to learn something new.
People like to be listened to.
Hear their dreams and their problems. Maybe they can do something for you too. Focus on Heaven. No one can run a race without looking at the finish line. We must remember that there is a reason for doing the things we do.
