Colossians 1:4
Since we heard of your faith in Christ Jesus and of the love that you have for all the saints — Paul's thanksgiving is triggered by report ('we heard,' akouō) of their faith and love. 'Faith in Christ Jesus' (pistis en Christō Iēsō) is trust-reliance on Christ. 'Love for all the saints' (agapē eis pantas tous hagiou) is communal love without boundary. The combination (faith in Christ → love for community) shows authentic discipleship: vertical faith produces horizontal love.
