These words in Philippians 1:3,4 express Paul’s love and delight and prayer life for people he had brought to Christ. As we know, that whole church was birthed through pain, suffering and imprisonment, yet Paul’s theme is JOY.
I thank my God for you, whenever I remember you (x2)
Always in every prayer of mine, making request for you all with joy (x2)
For your fellowship in the gospel, from the first day until now. (x2)
