Romans 10 : 17

And how shall they preach unless they are sent? As it is written: "How beautiful are the feet of those who preach the gospel of peace, Who bring glad tidings of good things!"
To believe they need to hear the word. Because the Word creates faith (Romans 10:17).
To hear the word someone needs to be sent. God is sending us each day.
Look up for the fields are white for harvest!
