6:6 Here is a specific example of mutual burden bearing. Perhaps the Judaizers were telling the Galatians not to support financially those who taught them. Under Judaism pupils paid a tax, and the teachers' pay came through the Jewish government. The Galatian Gentiles customarily paid fees for services rendered. The concept of voluntary giving out of love for the teacher was new and different. Those who learn from Bible teachers who provide the spiritual needs of others should provide them with "all good things"including their physical needs (cf. Luke 10:7; 1 Tim. 5:18; 1 Cor. 9:11, 14). Paul regarded the acceptance of gifts as a right one could claim or not claim depending on other factors. He did not regard accepting such gifts as the teacher's duty.
6:7-9 If a person selfishly withholds what he has, he will not see God multiply it and bless him with it. If he follows the prompting of his sinful nature in his investments, he will reap death, but if he follows the Spirit, he will reap life. This is not saying he will necessarily die but that his sowing will yield a disappointing harvest. Neither is it saying that he can earn justification. It is saying that his sowing will yield the best harvest. Our harvest will suffer if we grow weary and stop sowing. Remember that the context of this section is the support of Christian workers, though these principles certainly have wider application.
"Paul here seems to regard the whole of a man's earthly life as a period of sowing, with harvest awaiting him on the last day: the eschatological yield is determined by present sowing."212
The term "eternal life"has two different though related meanings in the New Testament. Essentially it is the life of God that He shares with believers. On the one hand, the New Testament writers spoke of it as a gift that one receives by faith (John 10:28; et al.). However it also refers to the quality of the believer's life that depends on the extent to which he or she walks with God in fellowship (John 10:10). In this second sense, some believers experience eternal life to a greater extent than other believers do. It is in this second sense that Paul spoke of eternal life here.213
"It is extremely important to note that in every place where eternal life is presented as something which can be obtained by works, it is contextually alwaysdescribed as a future acquisition. Conversely, whenever eternal life is described as something in the present, it is obtained by faith alone."214
The condition for this reward is not growing weary. The same expression describes a bow string that has become unstrung.215What causes this sad state is losing heart. Giving up mentally leads to growing faint spiritually.
"It is easy for the servants of God to become discouraged: the opposition they meet is so constant and the good they are trying to do is so hard to accomplish."216
