The natural man receiveth not the things of the Spirit of GOD: for they are foolishness unto him: neither can he know them, because they are spiritually discerned. But he that is spiritual judgeth all things, ...I cannot agree with your interpretation. I believe in "sola scriptura", and the premise "scripture interprets scripture" is a organic function of that belief. Your interpretation is "subjective", it doesn't cite scripture to interpret the symbols used in Revelation 13. In fact, it ignores scripture.
The Holy Spirit illuminates how scripture applies to us, so we repent and believe it, obey it. He aids our diligent study of scripture, seeking the answers to our questions in Scripture itself.
But from the vast diversity in interpretation of Revelation 13 among true believers, all filled with God the Holy Spirit aiding their study of scripture, its obvious God does not provide "a perfect and complete interpretation of Revelation 13.
And that explains how, even angels debate the meaning of scripture among themselves:
To them it was revealed that, not to themselves, but to us they were ministering the things which now have been reported to you through those who have preached the gospel to you by the Holy Spirit sent from heaven-- things which angels desire to look into (1 Pet. 1:12 NKJ)
Unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath, said the Lord-Matthew 25:29.
