Isaiah 54:17
No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the LORD, and their righteousness is of me, saith the LORD. No weapon that is formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn. This is the heritage of the servants of the LORD, and their righteousness is of me, saith the LORD.
No weapon formed against the servants of the Lord will succeed, and every tongue raised against them in judgment will be condemned, so that attacks fail and the servants themselves prevail over their accusers. This protection, defense and vindication is their heritage as the servants of the Lord, and their righteousness is from the Lord Himself as its source. It belongs to the church as it enters its final conflict clothed in Christ's righteousness, which must pass through trial and severe conflict before it triumphs, and God fulfills this protection for His people in these last days. That righteousness is freely given to those who hunger and thirst to receive it rather than earned by struggle or sacrifice, and it is found in Christ by feasting on the Word as the Bread of life. Its keeping is conditional on remaining separate and distinct as commandment-keeping doers of righteousness, and it calls God's messengers to stay faithful at their work amid opposition without being diverted by opponents.
Promise and Its Heritage
No weapon formed against the servants of the Lord shall prosper, and every tongue that rises against them in judgment they shall condemn. Attacks and accusations brought against them will not ultimately succeed or prevail, but will fail, and those who bring charges against them will themselves be condemned. The servants prevail against accusations raised in judgment, are able to answer those who condemn them, and remain safe and vindicated.
This protection, defense, safety, and vindication against weapons and tongues is the heritage belonging to the servants of the Lord. It is their heritage as the Lord's servants to be defended and to prevail rather than be overcome. Their righteousness is of and from the Lord Himself, and comes from Him. He Himself is the source of their righteousness, vindication, and protection.
The servants are a distinct, separate, and peculiar people consecrated to God under the banner of Jesus Christ. Established in righteousness, they are far from oppression and from fear and terror. Though enemies gather together against them, that gathering is not by God, and those who gather shall fall for their sake.
Accusations and decisions brought against God's chosen do not have the final say. Though they may be made through human prejudice and by agents of Satan, God's servants are ultimately vindicated.
Vindication in History and Prophecy
The promise belongs to the church as it enters its final conflict, clothed in Christ's righteousness. Weapons formed and accusations raised against God's servants will not prevail, those who bring charges against them in judgment will themselves be condemned, and their vindication and righteousness come from the Lord Himself as their heritage. Yet triumph comes only after endurance, for the church must pass through trial and severe conflict before prevailing. This protection is being fulfilled for God's people in these last days, with no weapon made to harm them succeeding and every accusing voice condemned. His salvation in this has already been seen in a remarkable manner, and it will continue to be seen.
In the time of trouble this defense becomes visible deliverance, when the wicked raise swords to kill the saints and the swords break and fall powerless. Their deliverance is part of God's promised protection that weapons raised against His servants will fail. So also when the liberty of Christ's church is endangered by oppression from transgressors of the Sabbath, God's people are not to be discouraged. Though that oppression looks like a great victory for evildoers and causes rejoicing among them, God has victory for His people.
Applied to the Bible itself, the same heritage means the war of infidels to overthrow Christianity and destroy the Bible cannot prosper. This includes the opposition raised in the French Revolution, where sustained attack did not diminish God's word. Like an anvil wearing out many hammers, the Bible has endured, continued to spread, and been greatly multiplied despite attack.
Righteous Life and Mission
The righteousness held out in the promise is not secured by struggle and toil, nor bought by gifts and sacrifice, but is freely given by the Lord Himself to all who hunger and thirst to receive it. That heritage is found in Christ, in knowing Him, receiving His attributes, and sharing His love and power. It is entered by receiving Christ as the heaven-sent teacher and feasting on the Word as the Bread of life, for belief in Him is essential to spiritual life. Those who so feast never hunger, never thirst, and never desire any higher good, because they possess the riches found in Him and are filled with the fulness of God. This inheritance is both a present joy and a heavenly reward.
To choose what is right because it is right, and to stand for truth though it brings suffering and sacrifice, is itself the heritage of the servants of the Lord, whose righteousness is of Him. Those who belong to God, are filled with Christ's love, and are armed with the gospel overcome by God and not by their own wisdom or strength, so opposition cannot prevail against them. Every attack and falsehood brought against them fails, and only makes those who stand firm stronger. The protection is conditional upon hungering and thirsting for righteousness, putting away foolishness and distractions that hold to the world, and teaching children the way of the Lord. It belongs to a commandment-keeping people who remain separate and distinct from the world as doers of righteousness; but if those entrusted with God's law break that law, He withdraws His protecting care, and they fall through perverseness and licentiousness and cannot stand before their enemies.
The assurance that weapons formed against them will not succeed, and that every accusing tongue raised in judgment will be condemned, encourages God's messengers to remain faithful at their work amid opposition. They are able to answer those who condemn them, and are not to be diverted by opponents or their claims. Together with Isaiah 55 and Isaiah 58, Isaiah 54 sets forth a precious and extensive work for God's people in the last days of this earth's history in serving others and bringing them the truth. That work is to lift up Christ before the world by working intelligently with God in true missionary labor, in public ministry and house-to-house work, proclaiming present truth in clear lines and in the power of the Spirit. Awakened from sleep, they are to do their God-given work in neglected cities with watchfulness, earnest faithfulness, separation from selfishness, eye-to-eye unity, and restored confidence through grace, not merely sitting in churches Sabbath after Sabbath listening to preaching, but visiting friends, neighbors, and families, creating interest, planting the Word in many hearts, and dealing out the bread of life to hungering souls to help them take hold upon eternal realities and be saved.
