6:10 {8} As we have therefore opportunity, let us do good unto all [men], especially unto them who are of the household of faith.
(8) Those that are of the household of faith, that is, those who are joined with us in the profession of one self same religion, ought to be preferred before all others, yet in such a way that our generosity extends to all.
6:10 Let us do good unto all [men]. Doing good is well doing, i.e. sowing to the Spirit.
Especially unto them who are of the household of faith. The Christian rule is to do good, but above all others to love, cherish and help the brethren.
6:10 Therefore as we have opportunity - At whatever time or place, and in whatever manner we can. The opportunity in general is our lifetime; but there are also many particular opportunities. Satan is quickened in doing hurt, by the shortness of the time, Rev 12:12. By the same consideration let us be quickened in doing good. Let us do good - In every possible kind, and in every possible degree. Unto all men - Neighbours or strangers, good or evil, friends or enemies. But especially to them who are of the household of faith. For all believers are but one family.
6:6-11 Many excuse themselves from the work of religion, though they may make a show, and profess it. They may impose upon others, yet they deceive themselves if they think to impose upon God, who knows their hearts as well as actions; and as he cannot be deceived, so he will not be mocked. Our present time is seed time; in the other world we shall reap as we sow now. As there are two sorts of sowing, one to the flesh, and the other to the Spirit, so will the reckoning be hereafter. Those who live a carnal, sensual life, must expect no other fruit from such a course than misery and ruin. But those who, under the guidance and influences of the Holy Spirit, live a life of faith in Christ, and abound in Christian graces, shall of the Spirit reap life everlasting. We are all very apt to tire in duty, particularly in doing good. This we should carefully watch and guard against. Only to perseverance in well-doing is the reward promised. Here is an exhortation to all to do good in their places. We should take care to do good in our life-time, and make this the business of our lives. Especially when fresh occasions offer, and as far as our power reaches.
