"And Jesus answered and said unto them, Take heed that no man deceive you. For many shall come in my name, saying, I am Christ; and shall deceive many" (Matthew 24:4,5).
This warning by Christ has special relevance in these latter days when there are multitudes of "false Christs, and false prophets" (Matthew 24:24), not only in the so-called "New Age" movement but also (in view of the fact that "Christ" means simply "anointed") in all kinds of religious, political, and educational areas of influence, and are, as Jesus warned, deceiving many. Therefore His urgent warning: "Take heed!"
This is a frequent emphasis in the New Testament. For example, Paul warned the Ephesian elders: "Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers. . . . For I know this, that after my departing shall grievous wolves enter in among you" (Acts 20:28,29). Note also the warning to the Hebrew believers: "Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God" (Hebrews 3:12). To anyone who feels overconfident in his own ability to withstand such deceptions and temptations, Paul warns: "Let him that thinketh he standeth take heed lest he fall" (I Corinthians 10:12).
Many similar warnings exist, and therefore we do well to take heed also to the safeguards that God has provided. "Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee" (I Timothy 4:16).
Continue in sound Biblical doctrine! For "We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place" (II Peter 1:19). HMM
