A.T. Robertson Commentary John 16:27

"for the Father himself loveth you, because ye have loved me, and have believed that I came forth from the Father." — John 16:27 (ASV)

Loveth (φιλε). Present active indicative of φιλεω, the word for warm and friendly love, here used of God's love for the disciples, while in 3:16 αγαπαω occurs of God's love for the world.

Ye have loved me (πεφιληκατε). Perfect active indicative of φιλεω, "loved and still love me warmly."

And have believed (πεπιστευκατε). Perfect active indicative again. Recall the exhortation in 14:1.
