The major problem most people have understanding the Bible is due to ignorance. It's easy to take snip-its and turn it into anything you want it to be. Study the Bible earnestly from beginning (Genesis 1:1 - "In the beginning, God created the heaven and the earth.) through the end (Revelation 22:20-21 - "He which tesifieth these things saith, 'Surely I come quickly'. Amen. Even so, come Lord Jesus. The grace of our Lord Jesus Christ be with you all. Amen.") and allow the Holy Spirit to open your heart to understanding. The "rules & regulations" of the Old Testament was for the Jews of ancient days when they had to offer sacrifices for sin atonements. However, as prophecied through out the Old Testament, God provided a way of salvation from eternal damnation and that way was through the death, burial & resurrection of the Lord Jesus Christ (and I do believe He was of virgin birth, led a sinless life & died for all who will accept his gift). Yes, God did & does judge sin. Study closely and you will see that God didn't let sin go unjudged or unpunished and He still doesn't. I look forward everyday to the trumpet sounding...(I Corinthians 15:52 - "In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.")
P.S. Please don't call me a "Bible Thumper". I have more respect for God and my Bible than that.
