For he is not a [real] Jew who is only one outwardly, nor is [true] circumcision something external and physical.

But he is a Jew who is one inwardly; and [true] circumcision is circumcision of the heart, by the Spirit, not by [the fulfillment of] the letter [of the Law]. His praise is not from men, but from God.

Certainly not! Let God be found true [as He will be], though every person be found a liar, just as it is written [in Scripture],

“That You may be justified in Your words,
And prevail when You are judged [by sinful men].”

It was to demonstrate His righteousness at the present time, so that He would be just and the One who justifies those who have faith in Jesus [and rely confidently on Him as Savior].

However, it is not as though God’s word has failed [coming to nothing]. For not all who are descended from Israel (Jacob) are [the true] Israel;

That is, it is not the children of the body [Abraham’s natural descendants] who are God’s children, but it is the children of the promise who are counted as [Abraham’s true] descendants.

That is true. They were broken off because of their unbelief, but you stand by your faith [as believers understanding the truth of Christ’s deity]. Do not be conceited, but [rather stand in great awe of God and] fear [Him];

But he who is uncertain [about eating a particular thing] is condemned if he eats, because he is not acting from faith. Whatever is not from faith is sin [whatever is done with doubt is sinful].

Let each one of us [make it a practice to] please his neighbor for his good, to build him up spiritually.
