1 Corinthians 9:24-27

When we say the Christian life is not easy, we mean that the Christian life will require us to do things we are not naturally inclined to do. We will be called upon to stop doing certain things we may want to do as well as to break bad habits. The Christian life requires us to fight sin and to love God and others, and if we are going to do those things, we must develop self-control to carry us through that battle. If we are going to live a life that pleases God and loves others, we must develop self-control that sets aside our worst qualities and moves us to the best. Gratefully, God does not leave us to develop this quality by ourselves, but He has sent His Holy Spirit to cultivate this quality in our lives as a spiritual fruit.
