“Spurgeon’s days saw apostasy as a trickle; by the time of the Bible League’s foundation  it had become a stream; shortly it expanded to a river , and today it has become a veritable ocean of unbelief. For the most of men the ancient landmarks have disappeared from sight. Life upon earth has become a voyage on an uncharted ocean in a cockle-shell boat ‘tossed to and fro, and carried about with every wind of doctrine.’ Never before in human history has the ‘sleight of men, and cunning craftiness, whereby they lie in wait to deceive’ (Eph. 4:14) been so greatly in evidence.” (S.M. Houghton, “The Bible League: Its Origin and Its Aims” 1971, Truth Unchanged, Unchanging, Abingdon: The Bible League, 1984).
1 Timothy 4:1 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
2 Timothy 3:13 But evil men and seducers shall wax worse and worse, deceiving, and being deceived.
2 Timothy 4:3-4 For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears; And they shall turn away their ears from the truth, and shall be turned unto fables.
2 Timothy 2:16 But shun profane and vain babblings: for they will increase unto more ungodliness.
Matthew 24:11-12 And many false prophets shall rise, and shall deceive many. And because iniquity shall abound, the love of many shall wax cold.
1 John 4:1 Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
