16 So I say, live by the Spirit, and you will not gratify the desires of the sinful nature.17 For the sinful nature desires what is contrary to the Spirit, and the Spirit what is contrary to the sinful nature. They are in conflict with each other, so that you do not do what you want. 18 But if you are led by the Spirit, you are not under law. 19 The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery;20 idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions 21 and envy; drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God.
22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness,23 gentleness and self‑control. Against such things there is no law.24 Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires.25 Since we live by the Spirit, let us keep in step with the Spirit.
We are completely unable to produce these fruits ourselves. They are fruits of the SPIRIT, and the SPIRIT must create them in us. Romans 8:7-8 tells us, "the sinful mind is hostile to God. It does not submit to God's law, nor can it do so.Those controlled by the sinful nature cannot please God." When we don't live in step with the Spirit, we will always give into our sinful, selfish nature. And every time we give into that, we grieve the heart of the God who gave all to save us.
