Is your friend a Christian? If not why do you need to take them to church? Why can't you be the witness instead of resting it on the shoulders of the church? To me the focus of church should be to fellowship with other believers, get lifted up, or lift someone else up, to be fed by the message.. kind of a break from the world. Its my (as in our) job to go out into the world to preach, not to go out into the world, to get people to come to church and hope the pastors message effects them.
