'One's' in the Bible

So then God’s choice is not dependent on human will, nor on human effort [the totality of human striving], but on God who shows mercy [to whomever He chooses—it is His sovereign gift].

Owe nothing to anyone except to love and seek the best for one another; for he who [unselfishly] loves his neighbor has fulfilled the [essence of the] law [relating to one’s fellowman].

Love does no wrong to a neighbor [it never hurts anyone]. Therefore [unselfish] love is the fulfillment of the Law.
