The Prayer of a Righteous Man

Can God hear the prayers of any but the righteous? Who is the this righteous man? How are we made righteous? What significance does the letter that begins each verse of this section have as an 'eye of the needle'? How are children being raised as tiny Pharisees by some? How do some see grace as something they need to 'go get'? How is a conversion renouncing yourself and following Christ alone? Why does the LORD show us our sinfulness as He did the rich, young ruler? Can anyone but Christ say they have hoped in His Word continually?
