“And even as they did not like to retain God in their knowledge, God gave them over to a reprobate mind, to do those things which are not convenient;” (Romans 1:28)
If you have been born-again, if you have been saved by grace through faith in the Lord Jesus Christ, crucified with Him, chosen before the foundation of the world, you will never be given over to a reprobate mind. You have the Holy Spirit residing within you, you cannot expel Him by any force of your will, Satan cannot pull Him out of you.
You are eternally saved, eternally loved, forever safe in the arms of the Living God.
But you will be chastised.
“For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth.” (Heb. 12:6)
There is no unpardonable sin, there is no sin that Christ did not take upon Himself on the cross, He bore every sin of every person who has or will ever live. You can grieve the Spirit, you can even quench Him, you can oppose Him at every turn, but He will never leave you or forsake you.
The unpardonable sin spoken of in Luke 12:10 cannot be done today, it bears reference to those who were attributing the works of the Lord Jesus Christ to Satan, those who will continue to deny Christ today and since that time are not saved and never will be, they are those who have been given over to that reprobate mind. “Having a form of godliness, but denying the power thereof: from such turn away.” (2nd Tim. 3:5)
There are and have been many throughout the ages who are indeed saved, those prodigal sons, so to speak, that left the fold to seek the pleasures of the world and never returned. The one in ninety-nine that the Lord goes to seek, yet refuse to return, here we run into the question for you in this short letter, and it revolves around these two verses.
“So likewise ye, when ye shall have done all those things which are commanded you, say, We are unprofitable servants: we have done that which was our duty to do.” (Luke 17:10)
And, “And cast ye the unprofitable servant into outer darkness: there shall be weeping and gnashing of teeth.” (Matt. 25:30)
I add two more for your contemplation as well. “They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us.” (1st John 2:19) And “Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?” (Matt. 7:22)
How do you know you are saved? What proofs outside of the feelings of your heart can you offer not only to others but to yourself that you are indeed saved by grace, an heir to the Kingdom of heaven? Can you show works done through you and at the same time by you through your willingness in submission to the Holy Spirit solely for the glory of God? Can you reveal not only to yourself but to those you meet a changed life, a life not even close to any resemblance to who you were before Christ?
Has your mind, your very nature been transformed by the Holy Spirit because of a love for the Savior, can you prove that you are no longer of the world?
Doubts can either cause one to despair or to take action, the assurance of our salvation and the unquestionable knowledge of that assurance does not rest in us, but in Christ.
Works cannot save us, but we are known by our works, our deceitful hearts can lie to us, but the Spirit of truth rests in us.
Are you a good person, or a saved person? Have you died to self for Christ, do you walk in humble service to Him, do you live for Christ, seeing death as gain? Is there any purpose in your life that outweighs seeing God glorified?
There are many with reprobate minds that believe they are saved, and there are many who truly are saved who are grieving the Holy Spirit, but there are none who have been born-again that He will ever leave or forsake.
