A whole day spent persuading, drawing on every scripture, points to the one work that matters inwardly. The kingdom of God is no place a person travels to, but the awareness of what he is and what his imagination can do. Convincing people of that takes patience, because the senses argue against it all day long.
And persuading concerning Jesus means bringing a person to accept the state he wants as already his. The whole labor from morning to evening is the labor of self-persuasion, holding a chosen conviction until it feels natural and undeniable. Conviction is the seed. A desire only takes root when a person is fully convinced of it within. That inner agreement, reached and held, is what afterward appears as the changed life outside.
