It is? Interesting for I find in my Bible. Jesus makes such a statement here in. Mat 19: [16] And behold one came and said to him: Good master, what good shall I do that I may have life everlasting? [17] Who said to him: Why asketh thou me concerning good? One is good, God. But if thou wilt enter into life, keep the commandments. [18] He said to him: Which? And Jesus said: Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness. [19] Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself. [20] The young man saith to him: All these I have kept from my youth, what is yet wanting to me?
[21] Jesus saith to him: If thou wilt be perfect, go sell what thou hast, and give to the poor, and thou shalt have treasure in heaven: and come follow me. [22] And when the young man had heard this word, he went away sad: for he had great possessions. [23] Then Jesus said to his disciples: Amen, I say to you, that a rich man shall hardly enter into the kingdom of heaven. [24] And again I say to you: It is easier for a camel to pass through the eye of a needle, than for a rich man to enter into the kingdom of heaven. [25] And when they had heard this, the disciples wondered very much, saying: Who then can be saved?
He says it again in the Gospel of John during His "I am the Vine" discourse :
[6] If any one abide not in me, he shall be cast forth as a branch, and shall wither, and they shall gather him up, and cast him into the fire, and he burneth. [7] If you abide in me, and my words abide in you, you shall ask whatever you will, and it shall be done unto you. [8] In this is my Father glorified; that you bring forth very much fruit, and become my disciples. [9] As the Father hath loved me, I also have loved you. Abide in my love. [10] If you keep my commandments, you shall abide in my love; as I also have kept my Father' s commandments, and do abide in his love.
