Paul highlights the importance of our focus and choices as Christians. Within the Christian life, there are two paths to follow: the way of the spirit of way of the flesh. As we live in accordance with the Spirit, God can produce a harvest in our lives, even if we don't immediately see the results. Likewise, our lives can be used powerfully by God as we become good stewards with God's resources. Growing spiritually is correlated with feeding the Spirit, as opposed to feeding the fleshly desires within our lives.
