An afterthought, Patrick: As was mentioned above, making genuine friendships with your housemates is likely the context in which you will most deeply impact them with what the Lord has given you. Also, keep in mind that it may (I wouldn't want to limit Him!) be the Lord will only give you one or a few of them to befriend on a deep level, and so influence their walks with Him.

A "servant-leader" heart is more attractive than a "gangbusters" (guns blazing) approach!
