Watchmen: 'Isaiah Would Go'

"Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me." Isaiah 6:8
"Some one, then, must undertake the ungracious task of probing and laying bare the evils of the age; for men must not be allowed to congratulate themselves that all is well. If others will not, he will.
If others shrink from the obloquy of such a work, he will not.... He loves his fellow-men too well. They may upbraid him; they may call him a misanthropist, or a prophet of evil; they may ascribe his warnings to the worst of motives, such as pride, or arrogance, or self-esteem, or malice, or envy; but he will give no heed to these unjust insinuations.
He will prefer being thus misunderstood and maligned, to allowing men to precipitate themselves upon a ruin which they see not. Rather than that they should perish, he will allow his own good name to be spoken against. He will risk everything, even the hatred of brethren, rather than withhold the warning. If they give no heed to it, he has, at least, saved his own soul. If they do, he has saved both his own soul and theirs.
He would rather take up the glad tidings of peace, and tell men of Him who came the first time for shame and death, and who is coming the second time for glory and dominion; but he feels as one who has a special and personal message to deliver, which cannot be postponed.
He must remember that he is a watchman; and, having seen danger pressing on, he must not hesitate to make it known. He must speak his message of forewarning and rebuke, sparing no arrows, and neither smoothing down nor hiding any form of sin, but laying his finger upon every sore, and beseeching men to turn from their ungodliness. The evils around him press upon him sadly; the coming evils are foreshadowed upon his spirit, and, therefore, he lifts up his voice like a trumpet.
Satan has many snares which need to be detected; the world has many spells and lures which must be disenchanted; religion has many guises which must be unmasked, many devious paths of inconsistency which must be pointed out, many cherished errors which must be condemned, many carnal taints which must be abhorred and shunned. All these he must protest against without fear or favour." Horatius Bonar 1808-1889
