6.13 Galatians -- Sow to the Spirit
Those who live by faith are not immune to the temptations of either Law or flesh. When sin occurs, the church is to confront the offender, but to do it in gentleness, and with the humility that comes from knowing that they may be the next to slip (Gal 6:1). Though Law is not the measure of behavior, man is still accountable for his deeds:
A man reaps what he sows (Gal 6:7).
The choice is either to live according to the old nature and perish, or according to the Spirit and live.
The New Testament social ethic is summed up:
As we have opportunity, let us do good to all people, especially to those who belong to the family of believers (Gal 6:10).
Here is a legitimate form of discrimination! The Bible does not command us to treat all people equally, as some modern idealists enthuse. While we are to seek to live at peace with all men, we are "to go the second mile" with other Christians. This is important: as God made a distinction in favor of the Jews in the Old Testament, so He bestows similar favor upon believers in the New.
Practically speaking, if you have a limited resource that you wish to share with others, do you go first to your own near neighbors or race, or to fellow believers of any background? Much of 2 Corinthians is Paul's answer to this question: he raised money among Macedonians and Corinthians to carry to Jerusalem, instead of having them give it to fellow Greeks who were in need. Thus while the Judaizers were creating divisions between the two communities, Paul was building international bonds of unity and common interest between them. This was a practical means of "sowing to the Spirit."
