Gal 5:16-25. The key to the Christian life is learning to yield to the Indwelling Spirit in us. Many Christians wrestle with the passions, cravings, and desires of sin, trying to get victory in their own strength, but we are told that if we walk in the Spirit, we will not fulfill the lusts of the flesh. Rather than constantly wrestling with the flesh, let us walk in the Spirit & enjoy the fruits that only he can produce in us.
