{If ye do} (ean poi(8874)e). Condition of third class with
ean and the present active subjunctive, "if ye keep on doing,"
not just spasmodic obedience. Just a different way of saying what
is in verse  10 . Obedience to Christ's commands is a
prerequisite to discipleship and fellowship (spiritual friendship
with Christ). He repeats it in the Great Commission ( Mt 28:20 ,
eneteilam(886e), I commanded) with the very word used here
(entellomai, I command).
