John Wesley Quote

I resolved to dedicate all my life to God, all my thoughts, and words, and actions; being thoroughly convinced, there was no medium; but that every part of my life (not some only) must either be a sacrifice to God, or myself, that is, in effect, to the devil. Can any serious person doubt of this, or find a medium between serving God and serving the devil?
