This question was asked by an article on Inquisitr on July 3rd of last year. This does seem to be a phenomenon that keeps appearing in different places. There are, of course, natural explanations for what is happening. As is pointed out in the Inquisitr, many Christians believe it is a sign that the end is near, but the mystery does have a natural explanation. In most instances the red color can be explained by a bloom of algae. In other cases the culprit is believed to be chemical contamination from nearby manufacturing plants. Whatever the reason, the blood red water is certainly an eerie sight.
My thought, however, is that just because we can find a natural explanation for these events, it doesn't necessarily mean that they do not have a supernatural cause as well. When the Bible predicts earthquakes will increase in the last days, that is a natural phenomenon with a supernatural cause. The blood red waters may also be a natural phenomenon (at least from the standpoint of being explainable by natural means), but that doesn't mean that God is not involved in it. We are certain of His prophecies, and we know that each one will come to pass. The fact that there is a natural and explainable cause is beside the point. If the event were predicted 2000 years ago and it happens exactly as predicted, then there is certainly a supernatural aspect to the prediction as well as the event.
On the other hand, we should also consider that these events may have a malevolent supernatural cause. If Satan can counterfeit the supernatural events that are already predicted, then he can use the counterfeit to discredit what is real (which he did in contending with Moses through the Egyptian Pharaoh). When Moses turned the water to blood, the magicians did something similar. This is Satan's way of getting people to believe that he is more powerful than God. But Satan's way is always counterfeit and deceptive, and fits the narrative of what happens to people left on earth after the Rapture of the Church as revealed by the Apostle Paul to the Church at Thessalonica.
2 Thessalonians 2:9-12
"When the wicked one appears, Satan will pretend to work all kinds of miracles, wonders, and signs. Lost people will be fooled by his evil deeds. They could be saved, but they will refuse to love the truth and accept it. So God will make sure that they are fooled into believing a lie. All of them will be punished, because they would rather do evil than believe the truth."
So, my advice to the Christian today is to not get overly concerned about any water turning blood red (unless, of course, it's the water pouring into your kitchen sink). The revelation of the blood-colored water appears in Revelation 16 which we know doesn't take place until AFTER the Rapture of the Church. The Revelation predictions, as well as all other remaining unfulfilled prophecy, will happen exactly as predicted in their proper time. The Church, fortunately, will already be in heaven when this takes place.
Does this mean that the events that are being witnessed are unimportant? I not suggesting that at all. What I want you to understand is this - there will be many prophetic events that will be fulfilled BEFORE the Rapture of the Church. But with the fulfillment of prophecy also comes the element of the unknown. Prophecy can be fulfilled right before our eyes and we may not understand its significance for many years to come. So it is difficult to point to certain predictions and state definitively that a certain event is its fulfillment. But one thing is certain. The Word of the Lord is sure. Not one jot or tittle will be lost, but all will be fulfilled. The predictions of Revelation, Daniel, Isaiah, Jeremiah and others will be fulfilled in the right way and at the right time. The end is near - even knocking at the door.
My advice to the unbeliever is to get ready NOW! You can't shun the gospel of Jesus Christ and expect a "get-out-of-jail-free" card when you finally realize that the Church is gone. If you reject Christ now, then great deception awaits you so that you will believe the lie and be forever condemned. You will stand before the Great White Throne at the final judgment without Christ and without hope. Your final destination will be the eternal lake of fire. Please don't wait. Jesus stands at the door of your heart and knocks, hoping you will open it and let Him in. Once you know you have eternal salvation you will never regret it.
