'Love's' in the Bible

yet for love’s sake I prefer to appeal to you—since I am such a person as Paul, an old man, and now also a prisoner [for the sake] of Christ Jesus—

There is no fear in love [dread does not exist]. But perfect (complete, full-grown) love drives out fear, because fear involves [the expectation of divine] punishment, so the one who is afraid [of God’s judgment] is not perfected in love [has not grown into a sufficient understanding of God’s love].
