Deductive reasoning is a way to use logic to deduce the answers to questions, but it's also used to deduce which questions we should be asking. We use a technique which we call deductive questioning.
Deductive Questioning

After his own heart is only ever used to refer to King David, who's a picture of someone who has complete faith that the power of God is available to do what's right and necessary.
