The Perfection of the Christian Life

The newness of our life therefore is this, that we walk in purity before God, eschew all corruption and uncleanness, and separate ourselves from all the defilements of the world, in order that we may offer ourselves in sacrifice to God; at the same time we must walk in integrity and uprightness with our neighbours. The performance of these two things is all that is requisite to the perfection of the Christian life.

– John Calvin, Sermons on Ephesians, p. 437
