Scripture readings:

Galatians 2:11–16 

But when Cephas came to Antioch, I opposed him to his face, because he stood condemned. For before certain men came from James, he was eating with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party. And the rest of the Jews acted hypocritically along with him, so that even Barnabas was led astray by their hypocrisy. But when I saw that their conduct was not in step with the truth of the gospel, I said to Cephas before them all, “If you, though a Jew, live like a Gentile and not like a Jew, how can you force the Gentiles to live like Jews?” 

We ourselves are Jews by birth and not Gentile sinners; yet we know that a person is not justified by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified.

Habakkuk 2:1–4

I will take my stand at my watchpost 
and station myself on the tower, 
and look out to see what he will say to me, 
and what I will answer concerning my complaint. 

And the Lord answered me: 

“Write the vision; 
make it plain on tablets, 
so he may run who reads it. 
For still the vision awaits its appointed time; 
it hastens to the end—it will not lie. 
If it seems slow, wait for it; 
it will surely come; it will not delay. 

“Behold, his soul is puffed up; it is not upright within him, 
but the righteous shall live by his faith.
