The basic premise is that you state that whatever you believe must have a plain-to-read source in the Bible. It will demand a principle of exegesis.
Eisegesis (/ˌaɪsəˈdʒiːsəs/; from the Greek preposition εἰς “into” and the ending from the English word exegesis, Greek ἐξήγησις, which in turn is derived from ἐξηγεῖσθαι “to lead out”) is the process of interpreting a text or portion of text in such a way that the process introduces one's own presuppositions, agendas, or biases into and onto the text. This is commonly referred to as reading into the text. The act is often used to “prove” a pre-held point of concern to the reader and to provide him or her with confirmation bias in accordance with his or her pre-held agenda.Wikipedia:Eisegesis (2017)
Exegesis (/ˌɛksəˈdʒiːsɪs/; from the Greek ἐξήγησις from ἐξηγεῖσθαι, “to lead out”) is a critical explanation or interpretation of a text, particularly a religious text. Traditionally the term was used primarily for work with the Bible; however, in modern usage “biblical exegesis” is used for greater specificity to distinguish it from any other broader critical text explanation.Wikipedia:Exegesis (2017)
Eisegesis is best understood when contrasted with exegesis. While exegesis is the process of drawing out the meaning from a text in accordance with the context and discoverable meaning of its author, eisegesis occurs when a reader imposes his or her interpretation into and onto the text. As a result, exegesis tends to be objective when employed effectively while eisegesis is regarded as highly subjective.Wikipedia:Eisegesis (2017)
