God has been working in the Samaritans. In the least expected people, God has been working.
John 4:36–38English Standard Version
Already the one who reaps is receiving wages and gathering fruit for eternal life, so that sower and reaper may rejoice together. For here the saying holds true, ‘One sows and another reaps.’ I sent you to reap that for which you did not labor. Others have labored, and you have entered into their labor.”
