Derek is someone I think of as above the Anti-FV blog meme, but he seems to be slipping down into it.
So what was Marx’s spiritual state? According to the Bible, he was someone who was delivered from “Egypt” but instead of following God to the Promised Land he stubbornly resisted God’s call in disbelief so that his “last state” became “worse… than the first” (2 Peter 2.20). This is not “Federal Vision.” It is the Apostle Paul:
For I want you to know, brothers, that our fathers were all under the cloud, and all passed through the sea, and all were baptized into Moses in the cloud and in the sea, and all ate the same spiritual food, and all drank the same spiritual drink. For they drank from the spiritual Rock that followed them, and the Rock was Christ. Nevertheless, with most of them God was not pleased, for they were overthrown in the wilderness. Now these things took place as examples for us, that we might not desire evil as they did. Do not be idolaters as some of them were; as it is written, “The people sat down to eat and drink and rose up to play.” We must not indulge in sexual immorality as some of them did, and twenty-three thousand fell in a single day. We must not put Christ to the test, as some of them did and were destroyed by serpents, nor grumble, as some of them did and were destroyed by the Destroyer. Now these things happened to them as an example, but they were written down for our instruction, on whom the end of the ages has come. Therefore let anyone who thinks that he stands take heed lest he fall. No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it. Therefore, my beloved, flee from idolatry.
Marx (who, by the way, was not only baptized but had, as far as anyone can tell, a quite convincing profession of faith in his youth), did not flee from idolatry. He embraced it. He invented a new form of it. So he died in the wilderness.
We should consider Marx a warning in history.
