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)
I have written you in my letter not to associate with sexually immoral people - not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world. But now I am writing you that you must not associate with anyone who calls himself a brother but is sexually immoral or greedy, an idolater or a slanderer, a drunkard or a swindler. With such a man do not even eat.
What business is it of mine to judge those outside the church? Are you not to judge those inside? God will judge those outside. (I Corinthians 5:9-13a,NIV)
As Christians our actions are to be governed by 'the fruit of the Spirit'. If the motivations listed among those 'fruit' are the impetus for our actions, then we have assurance of the actions' conforming to God's will. However, if our actions have any of the motivations which are listed as 'the acts of the sinful nature' as their impetus, then they are not conforming to God's will, even if those who are having their actions dictated by those motivations attempt to clothe them in piety.
So where does antisemitism and violence against nonbelievers have their underlying motivations found? Is it love and kindness, or is it hatred and fits of rage? Is it gentleness and self-control, or is it envy and selfish ambition? It doesn't take an 'Einstein' to answer those questions.
We Christians also need to recognize that those who are not among our fellow believers are to be left to God's judgement, and his alone. We are to concern ourselves solely with our own actions, as well as the actions of those among us who want us to accept them as fellow Christians. To desire to pass judgement on anyone who is outside the Church is to trespass on God's territory. Does anyone want to face him on that charge? I think not.
