'Physical' in the Bible

For a person is not a Jew because of his appearance, nor is circumcision something just external and physical.

When we were living in the flesh [trapped by sin], the sinful passions, which were awakened by [that which] the Law [identifies as sin], were at work in our body to bear fruit for death [since the willingness to sin led to death and separation from God].

For I could almost wish to be cursed and cut off from the Messiah for the benefit of my brothers, my own flesh and blood.

The ancestors are theirs, and from them, by physical descent, came the Messiah, who is God over all, praised forever. Amen.

That is, it is not the children by physical descent who are God’s children, but the children of the promise are considered to be the offspring.

For just as in one [physical] body we have many parts, and these parts do not all have the same function or special use,

But clothe yourselves with the Lord Jesus Christ, and make no provision for [nor even think about gratifying] the flesh in regard to its improper desires.
