Parallel
John 7:17
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Ἐάν τις θέλῃ τὸ θέλημα αὐτοῦ ποιεῖν, γνώσεται περὶ τῆς διδαχῆς, πότερον ἐκ τοῦ θεοῦ ἐστιν, ἢ ἐγὼ ἀπ’ ἐμαυτοῦ λαλῶ.
If anyone desires to do His will, he will know whether My teaching is from God or whether I speak on My own.
