1star, how about these scriptures:
Matthew 7:13-14 (KJV)
13Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:
14Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
Luke 18:18-22 (KJV)
18And a certain ruler asked him, saying, Good Master, what shall I do to inherit eternal life?
19And Jesus said unto him, Why callest thou me good? none is good, save one, that is, God.
20Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Honour thy father and thy mother.
21And he said, All these have I kept from my youth up.
22Now when Jesus heard these things, he said unto him, Yet lackest thou one thing: sell all that thou hast, and distribute unto the poor, and thou shalt have treasure in heaven: and come, follow me.
Luke 14:25-27 (KJV)
25And there went great multitudes with him: and he turned, and said unto them,
26If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple.
27And whosoever doth not bear his cross, and come after me, cannot be my disciple.
John 6:53-54 (KJV)
53Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you.
54Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day.
Matthew 18:2-3 (KJV)
2And Jesus called a little child unto him, and set him in the midst of them,
3And said, Verily I say unto you, Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven.
Matthew 5:17-20 (KJV)
17Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
18For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
19Whosoever 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.
20For 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.
John 3:3-8 (KJV)
3Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
4Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born?
5Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
6That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
7Marvel not that I said unto thee, Ye must be born again.
8The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
