Since Y2K (Year 2000AD) when the expectation of coming of our Lord Jesus Christ was not realized, many pastors and church leaders began to doubt the bible as the word of God. They then began to use worldly wisdom (demonic) for the understanding, comfort, security, advice, health etc. (James 3:14-16)
God used adverse weather conditions, earthquakes ,floods , famines and economic crisis to alert the Christians and to no avail but they still love this world and the things therein. The opinion of the world's experts that `global warming' caused all these calamities is accepted by these depraved Christian leaders thus ignoring the warnings by God. This shows that they are so depraved, worldly that they cannot hear from God anymore.
Thus, since the beginning of this Millennium, God had to use these types of signs with 5000 dead birds and 100,000 dead fishes and within 2 weeks after these miracles many birds, fishes, crabs and animals died in numerous area and countries worldwide. All the world experts have no answer and yet Christians are still sleeping or wallowing in the dirt of this world. They do not love God anymore otherwise they will hear Him and see His warnings.
These co-called `Christs' will misled Christians by discounted all His warnings with signs and wonders and finally God has to removed them if they do not repent with the deadly nuclear World War 3 killing 1/4 of all mankind.
