New Defender's Study Bible Notes
6:8 corruption. The word “corruption” here is actually that which leads to destruction, as in II Peter 2:12.
6:9 due season. The fruit reaped occurs in a later season than the sowing. It is of the same kind as the seed sown (I Corinthians 15:36-38; James 3:12), and is in proportion to the amount sown (II Corinthians 9:6-7). Yet it is of higher degree than the form in which it is sown (John 12:24).
6:9 faint not. The connotation of “faint” here is “relax.” The Christian must not relax in his ministry of seed-sowing, until the Lord comes (James 5:7-8).
