Rev 12:11 And they overcame him (Antichrist) by the blood of the Lamb and by the word of their testimony, and they did not love their lives to the death.
On top of understanding the blood of the Lamb, the overcomers will also need the Word of their testimony to defeat the devil and his deceptions and wicked schemes.
Word of their Testimony means their testimonies to His faithfulness in fulfilling His words, promises, prophecies, etc.
Mat 24:21, 24-25 "For then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be... For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect. See, I have told you beforehand"
In these last days the most fearful time will be the period of the great Tribulation. During this period false christs and false prophets will arise to deceive if possible the elect (godly Christians) with great signs and wonders.
See I have told you beforehand - I thank God that our Lord Jesus had warned us beforehand that these miracle workers are actually servants of Satan.
2Cor 11:13-15 For such are false apostles, deceitful workers, transforming themselves into apostles of Christ.
False christs - depraved church leaders, elders, bishops, pastors, etc. are actually servants of Satan and they can imitate the miracles of our Lord Jesus and His Apostles. Immediately after WW3, there will be great needs and these false christs will transform themselves into apostles of Christ by miraculously:-
1. Feeding the multitude,
2. Healing the sick, diseased, etc.
3. Giving them decent homes
4. Providing electricity and water
5. Providing food and basic needs
6. Many other miracles, etc.
All these miraculous righteous works are meant to deceive Christians to believe that they are disciples of Jesus.
2Cor 11:14-15 No wonder! For Satan himself transforms himself into an angel of light. Therefore it is no great thing if his ministers also transform themselves into ministers of righteousness, whose end will be according to their works.
False prophets are servants of Satan who will transform themselves as ministers of righteousness - imitating the miracles of Moses, Elijah, etc. They will also perform many other miracles in relief work by restoring houses, factories, power, transportation, etc. in unbelievable speed and ability.
John 14:29 "And now I have told you before it comes, that when it does come to pass, you may believe."
I thank God that our Lord Jesus had exposed all these deceptions of Satan and his cohorts in His end time teachings and we (esp new converts) must understand and teach them to avoid deceptions.
John 16:13 "However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come."
The Spirit of truth will also tell us the things in the future by helping us to understand the truth in end time events as recorded in the bible. No wonder, our Lord Jesus spent so much time warning us by giving in great details the persecutions, tribulations, wars, pestilences, deceptions of the false christs, false prophets and the Antichrist, etc. before Rapture. So brethren, let us understand the end time events and teach them to our sheep, so that they will become overcomers as they rejoice seeing each prophecy being fulfilled one by one.
