Holy Spirit
This chapter contrasts relying on ourselves for life-change rather than the Holy Spirit. Working to improve ourselves through our efforts will always be short-lived. Relying on the Holy Spirit will change our character from the inside and will be permanent. It doesn鈥檛 mean our efforts are useless; if we truly want to change, we will put forth an effort, but we must seek the Holy Spirit鈥檚 help.
Are you relying only on yourself for life-change? That鈥檚 probably not going well. Try asking God to have His Spirit work in you; to show you where you need to change; and help you make those changes.
