If that's what they need to do in order to come to Christ (I am all things to all men...), then that's our service to Christ and His body. We might be able to only plant a seed, we might be able to water, but the Holy Spirit will take care of the rest. We have recieved GRACE, not fairness, and are to be imitators of Him. They probably got the wrong idea, but not for long, they'll be back.
