Although one individual may possess both power and authority, the two are not identical. Authority is the right or responsibility to do something whereas power is the ability to do something. Unfortunately, the modern versions missed this truth when they translated Matthew 28:18. Instead of properly expressing that because of the resurrection the Lord Jesus had been given all power in heaven and earth, these so-called bibles suggest that He had been instead given authority. The authority already resided with Him, but the resurrection declared Him “to be the Son of God with power” (Romans 1:4). His resurrection from the dead gave Him the power over death by conquering the one who possessed the power of death (Hebrews 2:14).
Authority resides upon those who have the right to rule; but, unfortunately, it is not always combined with the ability to rule wisely. In the most basic sense, authority is the right and responsibility to rule others as given to one individual by another. The centurion in Matthew 8:9 expressed this truth when he said that his authority gave him the right to issue commands to his soldiers. The apostle Paul referred to his authority to call for the arrest and persecution of Christians (Acts 9:14; Acts 26:10, 12). This truth was also taught in the parable of the nobleman and his servants where the reward given was authority to rule over cities (Luke 19:17). Unfortunately, this desire for authority over others has been the source of problems and troubles throughout history.
Honest scientists are increasingly learning truths once deemed unimaginable by those who did not know the scriptures. Some of these truths concern the inner workings of man's mind and body. These relatively recent discoveries reveal that the body emits signals exposing truths intended by men to remain concealed. Sometimes the individual even lies attempting to conceal the facts further. For this reason, people began studying body language in hopes of determining if an individual's movements reveal otherwise hidden truths. Yet, the Bible has included these secrets long before man's scientific discoveries. In fact, the main character found in the oldest book of the Bible understood these principles. Job claimed that the truthfulness of his statements could be seen by simply looking at him. People have long assumed that the conscience is responsible for body language and the scriptures support this claim. Romans 9:1 confirms this truth as Paul stated, “I say the truth in Christ, I lie not, my conscience also bearing me witness in the Holy Ghost.” The Bible repeatedly shows that the conscience reveals the truth even when man intentionally tries to hide it, lie, or deceive.
