John 15:13

And that they might not underrate the measure of this exemplary love, He says, μείζονα ταύτης ἀγάπην … αὐτοῦ. Ταύτης is explained by ἵνα … αὐτοῦ as in John 15:8; and does not directly mean “than this which I have shown and still show,” as understood by Westcott and Whitelaw. It is a general statement, the application of which is suggested in John 15:14. Self-sacrifice is the high water mark of love. Friends can demand nothing more: there is no more that love can do to exhibit devotedness to friends, cf. Romans 5:6; Romans 5:8; Romans 5:10.
