How can they preach unless they are sent? As it is written, “How beautiful are the feet of those who bring good news!”
Romans 5:1-2
Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ, through whom we have gained access by faith into this grace in which we now stand. And we rejoice in the hope of the glory of God.
Romans 10:14
How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them?
