What was prayed? Something like: THANKS GOD revealed in Jesus, who is the rescuer now in charge. These folk trust Jesus and love those he has claimed because they now see that the most important treasure for them is stored in the unseen realm. They heard this truth, like so many, and are growing just like all different sorts of people who hear about the powerful generosity of God. These people heard it through a guy named Epaphras, (we love that guy) and he is the one who told us how real, and supernatural (Spirit led), their love is.
Then Paul wrote to the Colossians to tell them what he prayed:
Colossians 1:3-8 We always thank God, the Father of our Lord Jesus Christ, when we pray for you, (4) since we heard of your faith in Christ Jesus and of the love that you have for all the saints, (5) because of the hope laid up for you in heaven. Of this you have heard before in the word of the truth, the gospel, (6) which has come to you, as indeed in the whole world it is bearing fruit and growing–as it also does among you, since the day you heard it and understood the grace of God in truth, (7) just as you learned it from Epaphras our beloved fellow servant. He is a faithful minister of Christ on your behalf (8) and has made known to us your love in the Spirit.
What can we pray when we hear of a new Christian group?
Thanks God! (Not just any God, but the one revealed in Jesus as our Father). We heard about these people trusting you and caringly loving for others who trust in you. They do it because they believe that the best is protected for them in heaven. This is the same story that is happening in every nation imaginable, where real change and growth takes place. Someone actually was faithful and obedient in Christ to tell them, and they then reported about how real spiritual love is showing up in this new group.
