'Natural' in the Bible

For this reason God gave them over to degrading and vile passions; for their women exchanged the natural function for that which is unnatural [a function contrary to nature],

and in the same way also the men turned away from the natural function of the woman and were consumed with their desire toward one another, men with men committing shameful acts and in return receiving in their own bodies the inevitable and appropriate penalty for their wrongdoing.

I am speaking in [familiar] human terms because of your natural limitations [your spiritual immaturity]. For just as you presented your bodily members as slaves to impurity and to [moral] lawlessness, leading to further lawlessness, so now offer your members [your abilities, your talents] as slaves to righteousness, leading to sanctification [that is, being set apart for God’s purpose].

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].

If Christ lives in you, though your [natural] body is dead because of sin, your spirit is alive because of righteousness [which He provides].

For [if it were possible] I would wish that I myself were accursed, [separated, banished] from Christ for the sake [of the salvation] of my brothers, my natural kinsmen,

To them belong the patriarchs, and from them, according to His natural descent, came the Christ (the Messiah, the Anointed), He who is exalted and supreme over all, God blessed forever. Amen.

for if God did not spare the natural branches [because of unbelief], He will not spare you either.

For if you were cut off from what is by nature a wild olive tree, and against nature were grafted into a cultivated olive tree, how much easier will it be to graft these who are the natural branches back into [the original parent stock of] their own olive tree?
