Charles Ellicott 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)

For the Father himself loveth you, because ye have loved me.—(Compare to Notes on John 14:21; John 14:23). The reintroduction of this thought reminds us that, although in the fullness of the higher spiritual life there is communion between the Father and the human spirit—because the Father Himself always loves the heart that can receive His love—this power to receive the Father's love is itself the result of loving the Son, who has revealed Him.

Our Lord is leading them to the fuller truths of spiritual communion with God. He even tells them that this communion will be independent of mediation. Yet, the very words conveying this independence also affirm that everything depends upon His own mediation and the manifestation of God's love in His own person.

And have believed that I came out from God.—The reading is uncertain. Several of the better MSS. read, ...that I came forth from the Father. (Compare to the first words of the next verse and John 13:3). The perfect tenses represent their love and faith as completed and continuing in the present. It is striking that the order of the words makes faith follow love. This order may be chosen to mark emphatically the connection between the Father’s love for the disciples and their love for the Son; but it also suggests that their convictions were the result of having their hearts opened by love so that they received the truth.
