A.T. Robertson Commentary Luke 6:47

"Every one that cometh unto me, and heareth my words, and doeth them, I will show you to whom he is like:" — Luke 6:47 (ASV)

Hears and does (ακουων κα ποιων). Present active participles. So in Mt 7:24. (Present indicative.)

I will show you (υποδειξω υμιν). Only in Luke, not Matthew.
