Passage
Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.
Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.
Isaiah 1:16 Wash you, make you clean; put away the evil of your doings from before mine eyes; cease to do evil;
Isaiah 1:17 Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow.
Isaiah 1:18 Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.
Isaiah 1:19 If ye be willing and obedient, ye shall eat the good of the land:
Isaiah 1:20 But if ye refuse and rebel, ye shall be devoured with the sword: for the mouth of the LORD hath spoken it.
The verse centers on "come", "reason", "together", "saith", "lord", "though", "sins", and "scarlet". It is saying that the verse draws attention to "come" and "reason", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "Learn to do well seek judgment relieve..." into verse 19's "If ye be willing and obedient ye...", so "come" and "reason" belong inside that flow. In Isaiah context, the local focus is the Holy One of Israel, judgment and restoration, the servant of the LORD, and Zion's hope.
A plain takeaway is to answer the verse's own emphasis on "come" and "reason" with trust shaped by these words, not by a vague optimism outside the passage.
