Mr. E would severely have to disagree.
Salvation is found by and through faith on the Gospel of Christ, his death, burial and especially resurrection.
Resurrection is where a person is raised to new life, and that is where one can be in the rest that Jesus gives.
“And the Holy Spirit also testifies to us; for after saying, “This is the covenant that I will make with them After those days, says the Lord: I will put My laws upon their heart, And on their mind I will write them,” He then says, “And their sins and their lawless deeds I will remember no more.” Now where there is forgiveness of these things, there is no longer any offering for sin. Therefore, brethren, since we have confidence to enter the holy place by the blood of Jesus, by a new and living way which He inaugurated for us through the veil, that is, His flesh, and since we have a great priest over the house of God, let us draw near with a sincere heart in full assurance of faith, having our hearts sprinkled clean from an evil conscience and our bodies washed with pure water. Let us hold fast the confession of our hope without wavering, for He who promised is faithful; and let us consider how to stimulate one another to love and good deeds, not forsaking our own assembling together, as is the habit of some, but encouraging one another; and all the more as you see the day drawing near.”
Hebrews 10:15-25 NASB1995
“Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain. For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, and that He was buried, and that He was raised on the third day according to the Scriptures, and that He appeared to Cephas, then to the twelve. After that He appeared to more than five hundred brethren at one time, most of whom remain until now, but some have fallen asleep; then He appeared to James, then to all the apostles; and last of all, as to one untimely born, He appeared to me also. For I am the least of the apostles, and not fit to be called an apostle, because I persecuted the church of God. But by the grace of God I am what I am, and His grace toward me did not prove vain; but I labored even more than all of them, yet not I, but the grace of God with me. Whether then it was I or they, so we preach and so you believed.”
1 Corinthians 15:1-11 NASB1995
Paul, a bond-servant of Christ Jesus, called as an apostle, set apart for the gospel of God, which He promised beforehand through His prophets in the holy Scriptures, concerning His Son, who was born of a descendant of David according to the flesh, who was declared the Son of God with power by the resurrection from the dead, according to the Spirit of holiness, Jesus Christ our Lord, through whom we have received grace and apostleship to bring about the obedience of faith among all the Gentiles for His name’s sake, among whom you also are the called of Jesus Christ; to all who are beloved of God in Rome, called as saints: Grace to you and peace from God our Father and the Lord Jesus Christ. First, I thank my God through Jesus Christ for you all, because your faith is being proclaimed throughout the whole world. For God, whom I serve in my spirit in the preaching of the gospel of His Son, is my witness as to how unceasingly I make mention of you, always in my prayers making request, if perhaps now at last by the will of God I may succeed in coming to you. For I long to see you so that I may impart some spiritual gift to you, that you may be established; that is, that I may be encouraged together with you while among you, each of us by the other’s faith, both yours and mine. I do not want you to be unaware, brethren, that often I have planned to come to you (and have been prevented so far) so that I may obtain some fruit among you also, even as among the rest of the Gentiles. I am under obligation both to Greeks and to barbarians, both to the wise and to the foolish. So, for my part, I am eager to preach the gospel to you also who are in Rome. For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. For in it the righteousness of God is revealed from faith to faith; as it is written, “But the righteous man shall live by faith.””

Of course; Mr. E unbelief has its consequences. Loss of heavenly treasure above and outside of the kingdom.
