Joh 3:1 There was a man of the Pharisees, named Nicodemus, a ruler of the Jews:
Joh 3:2 The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.
Joh 3:3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
Joh 3:4 Nicodemus 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?
Joh 3:5 Jesus 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.
Joh 3:6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
Joh 3:7 Marvel not that I said unto thee, Ye must be born again.
This surely has to pertain to the New Testament.
Joh 4:10 Jesus answered and said unto her, If thou knewest the gift of God, and who it is that saith to thee, Give me to drink; thou wouldest have asked of him, and he would have given thee living water.
Joh 4:11 The woman saith unto him, Sir, thou hast nothing to draw with, and the well is deep: from whence then hast thou that living water?
Joh 4:12 Art thou greater than our father Jacob, which gave us the well, and drank thereof himself, and his children, and his cattle?
Joh 4:13 Jesus answered and said unto her, Whosoever drinketh of this water shall thirst again:
Joh 4:14 But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life.
This surely has to pertain to the New Testament.
Joh 5:24 Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.
This surely has to pertain to the New Testament.
Joh 6:32 Then Jesus said unto them, Verily, verily, I say unto you, Moses gave you not that bread from heaven; but my Father giveth you the true bread from heaven.
Joh 6:33 For the bread of God is he which cometh down from heaven, and giveth life unto the world.
Joh 6:34 Then said they unto him, Lord, evermore give us this bread.
Joh 6:35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
Joh 6:36 But I said unto you, That ye also have seen me, and believe not.
Joh 6:37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
Joh 6:38 For I came down from heaven, not to do mine own will, but the will of him that sent me.
Joh 6:39 And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day.
Joh 6:40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
This surely has to pertain to the New Testament.
And much more.
Mat 19:16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life?
Mat 19:17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
Mat 19:18 He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness,
Mat 19:19 Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.
Mat 19:20 The young man saith unto him, All these things have I kept from my youth up: what lack I yet?
Mat 19:21 Jesus said unto him, If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me.
Mat 19:22 But when the young man heard that saying, he went away sorrowful: for he had great possessions.
Some say this does not pertain to the New Testament,but the Old Testament,but that is not true,for the rich man wanted to know how to inherit eternal life,and Jesus said sell all you have and give to the poor.
Act 2:44 And all that believed were together, and had all things common;
Act 2:45 And sold their possessions and goods, and parted them to all men, as every man had need.
Act 4:32 And the multitude of them that believed were of one heart and of one soul: neither said any of them that ought of the things which he possessed was his own; but they had all things common.
Act 4:33 And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all.
Act 4:34 Neither was there any among them that lacked: for as many as were possessors of lands or houses sold them, and brought the prices of the things that were sold,
Act 4:35 And laid them down at the apostles' feet: and distribution was made unto every man according as he had need.
And that is what they did in the New Testament is sold all they had and it was given to the poor.
1Jn 3:17 But whoso hath this world's good, and seeth his brother have need, and shutteth up his bowels of compassion from him, how dwelleth the love of God in him?
1Jn 3:18 My little children, let us not love in word, neither in tongue; but in deed and in truth.
If any person has the means to feed the poor,but they do not do it,the love of God does not dwell in them,and people are more important than material things,and riches,to God.
That is why God said those that heap money to themselves have erred from the faith,for they neglect the poor.
There are many New Testament teachings of Christ,for He taught eternal life,and how to obtain it.
The Gospels are enough to save a person,so how are they not New Testament teachings,for saved is saved.
