In order for us to properly say and do what God wants of us, our original, sinful nature must be subdued, and a new nature implanted within us as the motivating force behind our words and actions. Those who try to use their original nature in the cause of Christ soon find that it is akin to trying to put a square peg into a round hole.
This Scripture passage should help you understand what this new nature consists of:
So I say, live by the Spirit, and you will not gratify the desires of the sinful nature. 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. But if you are led by the Spirit, you are not under law.
The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions 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.
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires. Since we live by the Spirit, let us keep in step with the Spirit. Let us not become conceited, provoking and envying each other. (Galatians 5:16-26,NIV)
The second paragraph of this passage tells us what the motivations are for the evil that we do. SOme are easy to identify, such as sexaul immorality and impurity. But others are more subtle, such as hatred, dissensions, and selfish ambition. But all of them can be placed under the heading 'narcissism', since they are evidence of a 'me first' mentality that pushes the needs of others aside in order to advance its own desires.
On the other hand, 'the fruit of the Spirit' listed in the third paragraph are evidence of a compassion for others that is more than just a veneer. With the motivations of love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control as the root cause of all that we say and do, our words and actions are 'in synch' with what God wants of us. And this is because in order for the words and actions to be in accordance with God's will, the underlying motivation for those words and actions must also be in accordance with God's will.
We cannot get good fruit from a poisoned tree. In like manner, we cannot perform good works unless the impetus for those good works is itself good. And that means accepting, and then using, the fruit of the Spirit as the point of origination for all that we say and do.
BTW, another benefit to using the 'fruit' as the impetus for what we say and do is that even if others disagree with you concerning our faith, they will still want to be around us because they know that they can trust us. And trust is important to everybody, not just Christians.
