Abundant Life?!?!?!

What is this abundant life? Many times we are told in the New Testament we are suppose to have life and have it abundantly through Jesus Christ. But what is the abundant life? A life where all of our wants are met? All of our needs are taken care of and all our wants are met too.
Personally I have to say that there is no way that this is the abundant life. Because every time it seems I get something that I want, I just want more, something bigger, something better…In our humanness we are never satisfied. C.S.Lewis said in Letters to Malcolm: Chiefly on Prayer, Bemused and besotted as we are, we still dimly know at heart that nothing which is at all times and in every way agreeable to us can have objective reality.” He is talking about the bad things from the Old Testament, and how can we believe our loving God could do such things. In this quote C.S. Lewis says that if everything always goes our way we will say that it is to good to be true. We can not always get our way, our human nature will make us question it, so what is the abundant life? What is this abundant life?
