The teachings of the Savior show that it is necessary to observe the ten commandments given through Moses. Upon one occasion a man asked what good thing he should do to gain eternal life. Jesus replied, "Keep the commandments," and then named some of them. (Matthew 19: 17, 18). {294} OTHER COMMANDMENTS. Besides the ten commandments, the Savior gave new ones which He said should be obeyed. Many of these are recorded in the fifth, sixth and seventh chapters of Matthew. TEST DOCTRINES BY CHRIST'S WORD. In our search for the true Gospel we can safely reject any teaching that does not agree with Christ's word. Anyone who says we can be saved without obeying His commandments is in error. "Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven." (Matthew 5: 19). "He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him." (I John 2: 4). Any teacher who adds to these any doctrines of men is a false teacher, and should not be followed. "In vain do they worship me, teaching for doctrines the commandments of men." (Mark 7: 7). MANY CLAIM TO BE TRUE TEACHERS. The teachers of many forms of religion claim that they teach these doctrines of the Gospel of Christ. How are we to decide which one is right? HOW FALSE TEACHERS MAY BE KNOWN. The Savior has furnished a test by which we can prove false teachers. He says, "Beware of false prophets." (Matthew 7: 15). He further adds, "Ye shall know them by their fruits." (10). "By their fruits" means by their works or by their teachings. False prophets or teachers teach falsehoods, and their works are evil. True prophets teach truth, and live righteously. They will not teach anything contrary to the words of the Savior. HOW TRUE BELIEVERS MAY BE KNOWN. The Savior tells us how we might know true believers. He says, "These signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues; they shall take {295} up serpents; and if they drink any deadly thing it shall not hurt them; they shall lay hands on the sick, and they shall recover." (Mark 16; 17, 18). The nineteenth verse of the sixteenth chapter of Mark states that these signs did follow the believers in the days of Christ's early apostles. These signs are outward evidences that people are true believers in the Gospel. The absence of them is a proof that faith is lacking, for the same cause will always produce the same effect. OTHER PROOFS. If a person truly believes in the Gospel, sincerely repents of his sins, is baptized for the remission of sins, and has hands laid upon him for the reception of the Holy Ghost, he should know that he has received the true Gospel.
