Once you are saved are you always saved? If you are struggling with the idea that you can lose your salvation, consider this less quoted passage from Romans 8.
Romans 8:28-31 NASB And we know that God causes all things to work together for good to those who love God, to those who are called according to His purpose.  For those whom He foreknew, He also predestined to become conformed to the image of His Son, so that He would be the firstborn among many brethren;  and these whom He predestined, He also called; and these whom He called, He also justified; and these whom He justified, He also glorified.  What then shall we say to these things? If God is for us, who is against us?
We will be specifically examining verses 29 & 30. Here are some questions for meditation:
- Did He (God) lose anyone between those He foreknew and those He predestined?
- Did He lose anyone between those He predestined and those He called?
- Did He lose anyone between those He called and those He justified?
- Did He lose anyone between those He justified and those He glorified?
Conclusion: Did you notice all of the verbs are past tense? Those whom He foreknew, He also glorified [Romans 9:23].
Rest assured God has a firm hold on you if you are following Christ [Luke 9:23-24].
