^^ I agree. My friend's church is a proponent of the idea that the church should be "pure", i.e. membership is only for those who are serious and 'sold out' to Jesus and live a life "victorious" over sin, which means: no smoking, no drinking, no fornication, no adultery,no divorce, no remarriage, and, a good, consistent Christian witness, etc. They simply cannot grasp the concept of a church which practises infant baptism and allows all sorts of loose and immoral people to be part of the membership. They are totally against "nominal" christians.
What I replied to my friend at the time was simply this: but shouldn't our first concern be our own life, our own sins? He did agree, but I knew in my heart he will never change his mindset. Never in a million years.
