Jesus of Nazareth truly said, "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life" (John 3:16). But he also said, "My sheep hear my voice, and I know them, and they follow me" (John 10:27). "Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father" (John 14:12). "If a man love me, he will keep my words" (Verse 23). "He that hath my commandments, and keepeth them, he it is that loveth me; and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him." (Verse 21.) "If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love." (John 15:10.) "Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven." (Matthew 7:21.) "And why call ye me, Lord, Lord, and do not the things which I say?" (Luke 6:46.) "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: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven. For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven." (Matthew 5:19-20.) "And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand: and the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it." (Matthew 7:26, 27.) "Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. Wherefore by their fruits ye shall know them." (Matthew 7:19.) When the rich young man asked the Savior what he should do that he might have eternal life, he was not told there was nothing for him to do but believe in Christ, but the answer was, "If thou wilt enter into life, keep the commandments." (Matthew 19:17.) After Christ's resurrection, when he sent his apostles into all the world to preach the gospel to every creature, he added, "Teaching them to observe all things whatsoever I have commanded you." (Matthew 28:20.)
