John Chrysostom, on Jas 5:20

“He must know that he who causeth a sinner to be converted from the error of his way, shall save his soul from death, and shall cover a multitude of sins.”

“And how do you go about converting someone? It is like the seeds sown by farmers. They are sown once, but they do not survive forever unless they are carefully nurtured. And unless the tillers of the soil protect the seeds, they will be exposed to the birds and to every seed-eating creature. We are just like this, unless we protect what has been sown in us by constant care, for the devil will snatch it away and our own lethargy will destroy it. The sun dries it up, the rain drowns it, and weeds choke it, so that it is not enough for the sower to pass by once only. Rather he must tend it often, driving away the birds of the air, pulling up the weeds and filling up the rocky places with much soil. He must prevent, block off and eject any form of destruction. Where soil is concerned, everything depends on the farmer, for without him it remains lifeless, ready only to suffer harm. It is not like that with spiritual soil however. For in spiritual matters it is not all up to the teachers; at least half the effort must come from the pupils. It is up to us the teachers to sow the seed but up to you the pupils to do the rest.”
