That is what Huck believes too. That's why he became an ordained minister in a Baptist church. However, you wander into dangerous theological waters (pun intended) when you imply that what man is constrained by also constrains God. God is all-powerfull and may grant grace regardless of what the Bible says if He wants to. Do you deny that he has that power?
God has said. I take that to be truth. God does not go back on His Word. If he has, please enlighten me.
If you believe that there is “possibly” other ways to be saved than what God has stated then why believe and abide by His Word? Talk about opening a pandora’s box. I mean opening the devil’s toolbox.
If Huckabee believes the literal Bible than why did he refuse to answer the question about Christians being the only ones saved?
Ephesians 2:8 “ For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:”
So what part of this verse leaves it open to be saved by means other than the Christian faith?
