“Blessed is the man to whom the Lord will not impute sin.” (Romans 4:8)
Not all, but many who believe that one must be baptized to be saved also believe that there are sins that they can commit that will cause them to lose their salvation, that the Almighty will revoke His gift and cast them away.
These people walk on eggs shells, as it were, for they were never quite sure if they have dishonored the Lord enough for that to happen. Inevitably their witness for Him is diminished so greatly that they are of little value to the Kingdom of the Living God, for their main concern is not about others, but about themselves.
How can one speak of eternal joy when that joy and eternal salvation may be ripped away from them by a singular mistake, when a wrong word or action can nullify the promises?
“If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.” (1st John 1:9)
Just what sins are so grievous in the eyes of the Lord that confession, even with a contrite and broken heart, would not be accepted by Him? Some who are thusly deceived will offer Matthew 12:31 at this time. “Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.” But not one of them can interpret this verse correctly, nor can they offer an explanation for it that can be held up by the Scriptures.
What say you then, is it cursing the Holy Spirit, calling Him a bad name, denying His authority? Just what sin can one who is truly born-again commit against the Holy Spirit that will cause the Most High to revoke your salvation and cast you into hell?
If there is one, then Romans 8:1 is a lie. “There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.”
Then John 10:29 was not written in truth. “My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father’s hand.”
If there is one, then the opening verse in this letter to you should be removed from the Word of God, along with all the others that show the proof of the assurance of salvation to all who believe on the Lord Jesus Christ.
Denying that the Lord Jesus Christ is the only way to the Father, that His shed blood must be mingled with some work of your own design, that God did not Him to be the propitiation for the sins of all mankind, that Jesus Christ is not the Holy Spirit, that the Holy Spirit is not God, that God is not Jesus Christ. That is the sin against the Holy Spirit, and no one who has been born-again can commit that sin, for all who do are not saved.
If you believe you must be baptized to be saved then you do not believe that the sacrifice of the Lord Jesus Christ was sufficient for the salvation of your soul, and you have committed a sin against the Holy Spirit.
If you believe that any work must be added to the cross, then your soul is in great peril.
“Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.” (1st Peter 2:24)
“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.” (Eph. 2:8-9)
If you will not accept the grace of God, then you have no other option than to look towards works, and no work of your own can add to His sacrifice, no work you offer will be accepted by the Almighty, if you have not been saved by grace through faith, then you are not saved.
The Lord Jesus Christ did not need you on that cross with Him, God the Father is not asking you to do anything but believe, believe what His Son did for you. Believe and be saved, attempt to add to it, and be rebuked, denied, lost.
No one who has been born-again can commit that sin, all who deny the sufficiency of the sacrifice of the Lord Jesus Christ already have.
