Any weapon whatever that will be formed against you will have no success, and any tongue at all that will rise up against you in the judgment you will condemn. This is the hereditary possession of the servants of Jehovah, and their righteousness is from me,’ is the utterance of Jehovah.”​—Isaiah 54:16, 17.

So today, even when the most powerful forces of this world attack Jehovah’s people, they will have no chance of ultimate success. How can that be?

27, 28. Of what can we be sure during these troubled times, and why do we know that Satan’s attacks against us will prove ineffective?

²⁷ The time for ruinous attack against God’s people and their worship with spirit and truth has passed. (John 4:23, 24) Jehovah allowed Babylon the Great to make one attack that proved temporarily successful. For a brief moment, “Jerusalem above” saw her offspring brought to near silence as the preaching work on earth ground to a virtual halt. Never again! Now she exults over her sons, for they are, in a spiritual sense, unconquerable. (John 16:33; 1 John 5:4) Oh, there have been weapons of attack formed against them, and there will be more. (Revelation 12:17) But these have not and will not succeed. Satan possesses no weapon that can quell the faith and burning zeal of the anointed and their companions. This spiritual peace is “the hereditary possession of the servants of Jehovah,” so no one can forcibly take it away from them.​—Psalm 118:6; Romans 8:38, 39.

²⁸ No, nothing that Satan’s world can do will ever put a stop to the work and enduring clean worship of God by his dedicated servants. The anointed offspring of “Jerusalem above” have taken great comfort in that assurance. Members of the great crowd do the same. The more we come to know about Jehovah’s heavenly organization and its dealings with his worshipers on earth, the stronger our faith will be. As long as our faith is strong, Satan’s weapons will prove to be futile in the fight against us!
