Romans 11:24

For if thou wast cut out of that which is by nature. wild olive tree, and wast grafted contrary to nature into. good olive tree; how much more shall these, which are the natural branches, be grafted into their own olive tree? "contrary to nature" -'The surprising thing is not that Jews can be brought back into the body of God's true people; they have (at that time) every spiritual and religious advantage. The strange thing is that Gentiles can be saved in spite of their inheritance of pantheism and atheism and idolatry...what is more natural on the part of. Jew than his return to the real faith of his fathers and his acceptance of the Messiah predicted by his prophets..?' (Erdman p. 139)
