Galatians, Chapter 2, verses 1-2, 7-14
1 He showeth when he went up again to Jerusalem, and for what purpose, 3 and that Titus was not circumcised, 11 and that he resisted Peter, and told him the reason, 14 why he and others, being Jews, do believe in Christ to be justified by faith, and not by worksLuke, Chapter 11, verses 1-4
1 Christ teacheth to pray, and that instantly11
11:1 Lord, teach us to pray, as John also taught his disciples - The Jewish masters used to give their followers some short formof prayer, as a peculiar badge of their relation to them. This it is probable John the Baptist had done. And in this sense it seems to be that the disciples now asked Jesus, to teach them to pray. Accordingly he here repeats that form, which he had before given them in his sermon on the mount, and likewise enlarges on the same head, though still speaking the same things in substance.And this prayer uttered from the heart, and in its true and full meaning, is indeed the badge of a real Christian: for is not he such whose first and most ardent desire is the glory of God, and the happiness of man by the coming of his kingdom? Who asks for no more of this world than his daily bread, longing meantime for the bread that came down from heaven? And whose only desires for himself are forgiveness of sins, (as he heartily forgives others,) and sanctification.
11:2 When ye pray, say - And what he said to them is undoubtedly said to us also. We are therefore here directed, not only to imitate this in all our prayers, but to use this very form of prayer. Mat 6:9.
11:4 Forgive us; for we forgive them - Not once, but continually.This does not denote the meritorious cause of our pardon; but the removal of that hinderance which otherwise would render it impossible.

2:1 Then fourteen years after - My first journey thither.I went up again to Jerusalem - This seems to be the journey mentioned Act 15:2; several passages here referring to that great council, wherein all the apostles showed that they were of the same judgment with him.
2:2 I went up - Not by any command from them, but by an express revelation from God. And laid before them - The chief of the church in Jerusalem. The gospel which I preach among the gentiles - Act 15:4, touching justification by faith alone; not that theymight confirm me therein, but that I might remove prejudice from them. Yet not publicly at first, but severally to those of eminence - Speaking to them one by one. Lest I should run, or should have run, in vain - Lest I should lose the fruit either of my present or past labours. For they might have greatly hindered this, had they not been fully satisfied both of his mission and doctrine. The word run beautifully expresses the swift progress of the gospel.
