10 So then, as occasion and opportunity open to us, let us do good (morally) to all people [not only being useful or profitable to them, but also doing what is for their spiritual good and advantage]. Be mindful to be a blessing, especially to those of the household of faith-those who belong to God's family with you, the believers. (Read: Galatians 6: 6-10).
9 The great hindrance to good sowing is weariness that results in discouragement and eventually in giving up. Four months elapse between planting and harvest (Jn 4:35); and, while it is true that in spiritual sowing the results may occasionally come sooner, more often they take much longer. The best reason for resisting weariness and giving up is that if the necessary preparation is done, the harvest is certain.
One cannot help feeling that Paul may be talking to himself as he thinks of the extensive but thus far unrewarding efforts he had expended on the churches of Galatia. The change to the first person plural supports this supposition.
10 Finally. Paul speaks broadly about the obligation to do good to all people, returning again primarily to the thought of giving money. But suppose a Christian is limited in resources? In that case, says Paul, he or she should give primarily to Christian causes, knowing that if they are not supported by Christians, they will not be supported at all. One with unlimited funds should give to every valid charity that comes along.
Two parts of this verse are of special interest. (1) Paul speaks of the "family of believers." This really means those who have become related to us by believing in Christ and points to a relationship transcending all others. Giving should not be unduly restricted by denominational or party loyalty. (2) Paul mentions "opportunity" (also translated "time" in v.9). This word denotes "proper time" for anything; consequently a time that occurs only once before it is lost forever. No one can hope to reap a harvest before the time appointed for it by God (v.9). But if one does not seize the time appointed for sowing, he or she will never reap a harvest.
