Is it wrong to say 'I just go by what Jesus says' in the Gospels?
Yes, it is just as ridiculous to say, 'I go by what Jesus says,' as returning to Leviticus and temple sacrifice, because the four Gospels are still 90% Jewish and have been set aside. God's program now follows progressive revelation, which directs believers into Paul's writings.
Les teaches that people have to get out of the four Gospels and get into Paul's writings, because the four Gospels are still 90% Jewish and that program has been set aside—it is no longer in God's program. He clarifies this does not mean throwing the Gospels away, any more than the Old Testament is thrown away. Yet he calls it just as ridiculous to say, 'Well, I go by what Jesus says,' as going back to Leviticus 5 and saying you cannot touch a dead thing because you must take a sacrifice to the altar at the temple. All these things must be put into perspective of the unfolding and progressive revelation, even of Paul's letters. He says the next study will be verse by verse in one of these prison epistles, constantly aware that God is no longer making any reference to the Jew or the Old Testament.
