One who believes in the Son has eternal life, but one who disobeys{The same word can be translated "disobeys" or "disbelieves" in this context.} the Son won't see life, but the wrath of God remains on him."

 Jesus said to Nicodemus: "I have tried to make things simple for you; I have used simple human pictures taken from everyday life; and you have not understood. How can you ever expect to understand the deep things, if even the simple things are beyond you?" There is a warning here for every one of us. It is easy to sit in discussion groups, to sit in a study and to read books, it is easy to discuss the intellectual truth of Christianity; but the essential thing is to experience the power of Christianity. And it is fatally easy to start at the wrong end and to think of Christianity as something to be discussed, not as something to be experienced. It is certainly important to have an intellectual grasp of the orb of Christian truth; but it is still more important to have a vital experience of the power of Jesus Christ. When a man undergoes treatment from a doctor, when he has to have an operation, when he is given some medicine to take, he does not need to know the anatomy of the human body, the scientific effect of the anaesthetic, the way in which the drug works on his body, in order to be cured. 99 men out of every 100 accept the cure without being able to say how it was brought about. There is a sense in which Christianity is like that. At its heart there is a mystery, but it is not the mystery of intellectual appreciation; it is the mystery of redemption.
