Acts 9:31 Then the churches throughout all Judea, Galilee, and Samaria had peace and were edified. And walking in the fear of the Lord and in the comfort of the Holy Spirit, they were multiplied.
It is only after trouble and strife that you begin to see peace as the stark contrast to what was before and what is now.
The disciples had to put up with a lot of people working against them, people trying to put them in jail and even some trying to kill them.
The peaceful stage they reached after this all was a marked difference to what had gone before; but they did not stop and rest, they continued to preach and share God’s love with everyone.
