There is an inflow from God into us. This is obvious from everyone’s ready admission that everything good that is truly good and that exists in us and is done by us is from God. The same admission applies to everything related to goodwill and faith. For we read, “We cannot receive anything unless it is given to us from heaven” (John 3:27). And Jesus said, “Without me you cannot do anything” (John 15:5), meaning anything having to do with goodwill and faith.
This inflow comes into our souls because the soul is the inmost and highest part of us. The inflow from God reaches that part first and then comes down into the things below and enlivens them, depending on our openness to what flows in. Of course, truths that will become part of our faith do indeed flow in through our hearing and are implanted in our mind, which is below the soul; but all these truths do is prepare us to accept what flows in from God through our soul. The quality of that preparation determines the quality of our acceptance and of the transformation of our earthly faith into spiritual faith.
