Colossians 1:8

Your love in the Spirit - So we preached, and so ye believed. The heavenly flame in the heart of this minister communicated itself to those who heard him; it was like priest like people. They enjoyed a spiritual, energetic ministry, and they were a spiritual people; they had a loving spirit, and love through the Spirit of God which dwelt in them. And of this love of theirs in the Spirit, and particularly towards the apostle, Epaphras gave full proof, not only by describing to the apostle the affection they felt for him, but in presenting to him those supplies which their love to him caused them to furnish.

Who also declared unto us your love in the Spirit - The love wrought in you by the Holy Spirit. It was not mere natural affection, but love worked in their hearts by the agency of the Holy Spirit.

1:8 Your love in the Spirit - Your love wrought in you by the Spirit.
