That postulates a two-fold process for a person to accept Christ --
first, a willingness to "listen to" the claims of theism without
rejection out-of-hand and, second, a willingness to "listen to" the
claims of Christ.
While it may seem more complex than necessary, as I read C. S. Lewis's
account of his conversion experience(s), that fits. It also fits my own.
I suspect it does not fit everyone's experience -- nor even most
everyone!
