Pagans speak ill of others and find it difficult to praise people. They criticize, gossip, and lie. Christians, as children of God who have his character, speak well of others whenever possible and engage in the gossip of love.
[Epaphras] also told us of your love in the Spirit.
Colossians 1:8 NET
Several times the New Testament connects love to the Holy Spirit. Love is the fruit of the Spirit. The Spirit is the channel through whom God gives us his love; first, through the revelation of the history of Christ and, second, through the habitation of the Spirit in us as the active agent of love.
The love of the Colossians was alive and real, so notable that Epaphras reported to Paul about it.
Whoever seeks for love in God’s people will find and praise it.
