"The paganisation of Christian doctrine for which hell has been a bulwark has entrenched a dualism and an image of God's power as primarily destructive and terrifying. "
Right here is the perfect example of the error of the "Hell No" crowd.
God however said Luke 16:22-24 .....
"And it came to pass, that the beggar died, and was carried by the angels into Abraham's bosom: the rich man also died, and was buried; 23And in hell he lift up his eyes, being in torments, and seeth Abraham afar off, and Lazarus in his bosom. 24And he cried and said, Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue; for I am tormented in this flame."
So again we are challenged to accepted YOUR opinion, (or someone Blog) or the word of God!
