God can testify how I long for all of you with the affection of Christ Jesus. (Php 1:8)
Apostle Paul was very confident how much he loved his members in the gospel, and said that God was the witness to his love for them. We can feel the heartfelt sincerity of Apostle Paul who loved his brothers with all his heart and soul.
Nobody might acknowledge it, even though you make much effort and shed tears for brothers and sisters. But it shouldn’t matter because God knows all your invisible efforts, zeal, and love for them, as it is written, “God can testify.” Let’s give thanks to God for being a witness to every work we do, and make even more efforts to love our brothers and sisters anytime anywhere.
