4:28 Now we - Who believe, whether Jews or Gentiles.Are children of the promise - Not born in a natural way, but by the supernatural power of God. And as such we are heirs of the promise made to believing Abraham.

4:29 But as then, he that was born after the flesh persecuted him that was born after the Spirit, so it is now also - And so it will be in all ages and nations to the end of the world.

4:30 But what saith the scripture - Showing the consequence of this. Cast out the bondwoman and her son - Who mocked Isaac.In like manner will God cast out all who seek to be justified by the law; especially if they persecute them who are his children by faith. Gen 21:10.

4:31 So then - To sum up all. We - Who believe. Are not children of the bondwoman - Have nothing to do with the servile Mosaic dispensation. But of the free - Being free from the curse and the bond of that law, and from the power of sin and Satan.

5:1 Stand fast therefore in the liberty - From the ceremonial law.Wherewith Christ hath made us - And all believers, free; and be not entangled again with the yoke of legal bondage.

5:2 If ye be circumcised - And seek to be justified thereby.Christ - The Christian institution. Will profit you nothing - For you hereby disclaim Christ, and all the blessings which are through faith in him.

5:3 I testify to every man - Every gentile. That is circumcised - He thereby makes himself a debtor - Obliges.

5:4 Therefore Christ is become of no effect to you - Who seek to be justified by the law. Ye are fallen from grace - Ye renounce the new covenant. Ye disclaim the benefit of this gracious dispensation.

5:5 For we - Who believe in Christ, Who are under the gospel dispensation. Through the Spirit - Without any of those carnal ordinances.Wait for - in sure confidence of attaining. The hope of righteousness - The righteousness we hope for, and full reward of it. This righteousnesswe receive of God through faith; and by faith we shall obtain the reward.

5:6 For in Christ Jesus - According to the institution which he hath established, according to the tenor of the Christian covenant.Neither circumcision - With the most punctual observance of the law.Nor uncircumcision - With the most exact heathen morality.Availeth anything - Toward present justification or eternal salvation.But faith - Alone; even that faith which worketh by love - All inward and outward holiness.

5:7 Ye did run well - In the race of faith. Who hath hindered you in your course, that ye should not still obey the truth?

5:8 This your present persuasion cometh not from God, who called you - to his kingdom and glory.

5:9 A little leaven leaveneth the whole lump - One troubler, ver. Gal 5:10, troubles all.

5:10 Yet I have confidence that - After ye have read this. Ye will be no otherwise minded - Than I am, and ye were. But he that troubleth you - It seems to have been one person chiefly who endeavoured to seduce them. Shall bear his judgment - A heavy burden, already hanging over his head.

7:1 Coming from Jerusalem - Probably on purpose to find occasion against him. Mat 15:1.

7:4 Washing of cups and pots and brazen vessels and couches - The Greek word (baptisms) means indifferently either washing or sprinkling. The cups, pots, and vessels were washed; the couches sprinkled.

7:5 The tradition of the elders - The rule delivered down from your forefathers.

7:6  Isa 29:13.
