Lutherans gave me a love for the Bible. Pentecostals, a love for the Spirit. Reformed, a theology of the atonement. Congregationalists, a view of church government. Baptists, a method of baptism. Methodists, lessons on prayer. Catholics, GK Chesterton.
In a free society, it's often much easier to criticise external structures, movements, churches, politicians, etc, than it is to identify and repent of our own sin.
'The Christian church sings...from inner necessity it sings. It's the highest form of expression...the church which doesn't sing isn't the church. Where it doesn't really sing but sighs & mumbles it is only a troubled community which is not sure of its cause.'
