Christians, Catholics, and Atheists please answer this question?

Question

This is a re-post because I forgot to post my scriptures earlier.

I have some verses that I want you to read. Take your time and explain to me IN YOUR OWN WORDS what you believe the message is in these verses. It is important that you list denomination, religion, or if Atheist. Atheists, since you have no denominational ties to any Church, your opinion is important to me, and in answering the question you are only telling me what you believe it is saying, not that you believe it. I am not preaching to you. My goal is to gain knowledge of what this means to unbelieversrs and the different denominations. So to any who may feel tempted, please refrain from making derogatory statements and be respectful with your answers.

Hebrews 6

4 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,

5 And have tasted the good word of God, and the powers of the world to come,

6 If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.

Answer 1

One can only receive forgiveness by faith and that is God's gift.  If one by apostasy has lost that faith then he cannot receive forgiveness. However, what is impossible for man is not impossible for God. If one has by conscious rejection of the truth hardened his heart to the voice of God through the Holy Spirit and refuses to listen then, of course, he will not repent and ask for forgiveness. If however, by the mercy of the Holy Spirit, he feels convicted  of his sinfulness and seeks God's forgiveness, then he shall have it.  I know this to be true because although I consciously denied Christ after having been a Christian and worshipped other gods, by the mercy of the Holy Spirit I was given awareness of my offenses to God and sorrow for it and the desire to return to Him and He  took me back and forgave me and filled my heart with heaven. He will never turn away one who truly repents and wants to return to Him, just as a parent would never turn away a returning child.   This verse is meant as a warning, because the harder  we make  our hearts towards God by disobedience the deafer we become to his voice. I was almost at the point of atheism, when he pulled me back from the brink.  (and of course, without believing that Christ can forgive sins because he is the Son of God then one won't approach him for forgiveness).  As long as we remain in our willful disobedience and do not acknowledge our sinfulness, we cannot return. There is no guarantee that we will regain the faith we need to repent and return.  (It is not something that we can muster up on our own -- faith is God's gift) Therefore, we should never take disobedience to God lightly.  Still, even the greatest sinner, if he seeks to return to God can be assured that God is unfathomably merciful and will not turn him away. - Lutheran Christian

Answer 2

I'm atheist, for me it say that real apostates and former members of the a Church Hierarchy, leaving while conscious of what they leave, never comes back and have a tendency to attack what they formerly supported. The whole expressed with the vocabulary of a Christian cult.
