Knowing the Salvation teaching of the Bible & Apostle Paul is necessary when studying verses such as Heb 6:4 thru 6:6. Since the Bible is God inspired, there can be no significant differences in doctrinal matters. The Apostle Paul would not change his salvation teaching among his many Epistles. Likewise, the same is true among the Books of the Bible. These are prerequisites to interpreting & understanding any verse, or group of verses in the Bible.
Below you will find verses, which show the Salvation Teaching of both the Bible & Apostle Paul. The selections contain a limited number of verses, with links to other pages dealing with in-depth listings of appropriate verses. This was done because I realize that it becomes tedious to go through a long listing of verses, which basically say the same thing. It becomes counter productive to a study.

"We know that in all things God works for good with those who love him, those whom he has called according to his purpose.
Those whom God had already chosen he also set apart to become like his Son, so that the Son would be the first among many believers.
And so those whom God set apart, he called; and those he called, he put right with himself, and he shared his glory with them."
"Let us give thanks to the God and Father of our Lord Jesus Christ! For in our union with Christ he has blessed us by giving us every spiritual blessing in the heavenly world.
Even before the world was made, God had already chosen us to be his through our union with Christ, so that we would be holy and without fault before him. Because of his love God had already decided that through Jesus Christ he would make us his children---this was his pleasure and purpose."
"God saved you through faith as an act of kindness. You had nothing to do with it. Being saved is a gift from God."
