As Apostle Paul, inspired by Holy Spirit, wrote to Philemon, this passage was preserved for each of us to read and be encouraged also.As we share our faith with one another, and with others, our faith will get stronger, will become more powerful in sharing the Love, Good News of the Salvation message of our Lord Jesus.
Also, the more we share our faith, the more imbedded it becomes in our spirit, and the more we will be open and free to share as the Spirit leads.
