"For I long to see you, that I may impart to you some spiritual gift, to the end you may be established; (12) That is, that I may be comforted together with you, by the mutual faith both of you and me."
Paul's letter to the Romans was written from Corinth during his 3rd visit there in A.D.60. It is addressed "To all that be in Rome, beloved of God, called to be saints:" (Rom.1:7).
After his usual offerings of grace and peace there is an expression of gratitude towards the Roman Christians because they have made their faith known, and not hidden it away in some secret corner,(Rom.1:8). We too can be grateful for those who have made their faith known in our lives as well. In the 1970's I was in and out of church fellowship like an ocean tide, and my faith was quite erratic, but it seemed that wherever I went saints kept testifying to me and I was eventually urged by the Holy Spirit to admit to the value of continuing in regular communion with the body of Christ.
