Justification - Exegesis v. Eisegesis
Some passages of Scripture are crystal clear in terms of their meaning, while others are less clear. Though confirming the fact that Peter viewed Paul's writings as Scripture, he admitted to finding some of Paul's letters "hard to understand."
"There are some things in them that are hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other Scriptures." (2 Peter 3:16)
One of the basic rules of hermeneutics (the science of biblical interpretation) is that on any given subject, we start with passages that are clear on the issue before moving to what is seemingly unclear (at least at first). When seeking to understand an issue, we must start with passages that actually address the subject in the Bible, and this will allow us clarity when seeking to understand the doctrine in possible inferences made elsewhere in Scripture.
In terms of the biblical doctrine of justification and whether someone who is genuinely justified has the possibility of losing that salvation, passages such as Romans 8:28-39 come to mind because of its sheer clarity. Here we read:
28 And we know that for those who love God all things work together for good, for those who are called according to his purpose. 29 For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers. 30 And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified.
31 What then shall we say to these things? If God is for us, who can be against us? 32 He who did not spare his own Son but gave him up for us all, how will he not also with him graciously give us all things? 33 Who shall bring any charge against God's elect? It is God who justifies. 34 Who is to condemn? Christ Jesus is the one who diedâ€”more than that, who was raisedâ€”who is at the right hand of God, who indeed is interceding for us.
35 Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or danger, or sword? 36 As it is written, â€œFor your sake we are being killed all the day long; we are regarded as sheep to be slaughtered.â€
37 No, in all these things we are more than conquerors through him who loved us. 38 For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, 39 nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.
What follows below is an interesting interchange on youtube video between a Roman Catholic caller and Dr. James White on his Dividing Line program. I think it shows a clear comparison between exegesis (drawing out the meaning from the text) and eisegesis (reading into the text). - JS
