SirStrengthenDiscipline-
We Christians have two natures. One we were born with, adn that nature we call 'the sinful nature'. But there is another nature which is given to us as a consequence of our accepting Christ, and this nature is called 'the fruit of the Spirit'. Paul describes both of these natures in this passage:
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 acts of the sinful nature are the desires and motivations which are the origin of every sinful act ever committed. They are also at the very core of our original, sinful nature, so their being subdued is beyond our power. But it is not beyond God's own power, and he is quick and willing to use this power in order to conquer it.
But it doesn't end there. He is also willing and able to implant in us a new nature, which we call 'the fruit of the Spirit'. And just as 'the acts of the sinful nature' are to be seen as the impetus for every sinful act committed, 'the fruit of the Spirit' is to be seen as the impetus for every righteous act performed. These 'fruit' are the borders within which all our words and actions have assurance of being 'in synch' with God's will. There is no need to fear his wrath, because by permitting the fruit of the Spirit to be the origin of everything that we say and do, those words and actions will be in accordance with what God himself wants of us.
We all have a spiritual Achilles' heel, a particular weakness that affects us more than other motivations might. What we need to recognize is that this weakness is only part of a set of motivations which are our old nature, and that entire set is what the Spirit is capable of reining in for us. So we put our trust in his power and strength, while accepting the new nature that he has brought with him as the impetus of every word and action that we will say and do from this time forward.
God bless-
