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. – Isaiah 54:17

O, blessed be the name of the Lord! “no weapon that is formed against the church shall prosper.” We glory because we can put our finger upon history and exclaim, God is true, and events are witnesses of His faithfulness. O beloved, has the Holy Ghost given you an inwrought knowledge of the truth of this word of God? Have you experienced blessed deliverances from the right hand of the Most High? Many of you, I fear, have neither part nor lot in this matter, and you have true cause to lament your terrible loss in being unable to grasp these covenant blessings. But some of us may now anticipate the hour when we shall obtain complete redemption with all the blood-bought family, and then, ah, then, how shall we with rapture review delivering grace in all its thousand instances! Hark! hark! methought I heard sweet music; methought I heard a song descending from the regions up above, borne down by gales whose breath is sweet as that which comes from the spicy groves of Araby. I hear a sound not earthly: it is, it must be, celestial, for no mortal sonnets can with these compare. O river of harmony! Where are the lips from which thou flowest? …Holy ones, repeat the song; saints of God, re-echo the chorus; repeat it yet again, that these ears may hear it. What do you sing? “No weapon that is formed against us hath prospered; every tongue that hath risen against us in judgment we have condemned.” This is the heritage-“Our righteousness is of the Lord.” ~ C.H. Spurgeon
