Follow certainly means obey.
What you can't prove is that any kind of behavior or lifestyle results in having eternal life. What I HAVE proved from Scripture is that eternal life is received on the basis of believing in Christ.
Only then is lifestyle and behavior an issue for the believer. And lifestyle and behavior is NEVER an issue for an unbeliever to become saved.
How can a disciple follow his teachers instruction if he doesn’t obey him?
He can't, and this is irrelevant to the issue.
The result of hearing His Voice and following Him is receiving eternal life.
Again, what you CANNOT PROVE is that there is anything in John 10:27 that RESULTS in receiving eternal life.
The following verses tell us clearly HOW to receive and have eternal life:
Salvation:
Mark 16:16 " He who has believed and has been baptized shall be saved; but he who has disbelieved shall be condemned.
Luke 8:12 "Those beside the road are those who have heard; then the devil comes and takes away the word from their heart, so that they will not believe and be saved.
Acts 4:12 "And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved."
Acts 11:14 and he will speak words to you by which you will be saved, you and all your household.'
Acts 16:31 They said, “Believe in the Lord Jesus, and you will be saved, you and your household."
Rom 10:9, 10 9 that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; 10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.
Rom 1:16 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.
1 Cor 1:21 - For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe.
Eph 2:8 For by grace you have been saved through faith; and that not of yourselves, it is the gift of God;
2 Tim 3:15 and that from childhood you have known the sacred writings which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus.
1 Peter 1:5 who are protected by the power of God through faith for a salvation ready to be revealed in the last time.
1 Peter 1:9 obtaining as the outcome of your faith the salvation of your souls.
2 Thess 2:13 But we should always give thanks to God for you, brethren beloved by the Lord, because God has chosen you from the beginning for salvation through sanctification by the Spirit and faith in the truth.
Eternal Life:
John 3:15-16 15 so that whoever believes will in Him have eternal life. 16 "For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.
John 3:36 "He who believes in the Son has eternal life; but he who does not obey the Son will not see life, but the wrath of God abides on him."
John 5:24 "Truly, truly, I say to you, he who hears My word, and believes Him who sent Me, has eternal life, and does not come into judgment, but has passed out of death into life.
John 6:40 "For this is the will of My Father, that everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day."
John 6:47 "Truly, truly, I say to you, he who believes has eternal life.
Rom 6:23 For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord
1 Tim 1:16 Yet for this reason I found mercy, so that in me as the foremost, Jesus Christ might demonstrate His perfect patience as an example for those who would believe in Him for eternal life.
Gal 3:22 But the Scripture has shut up everyone under sin, so that the promise by faith in Jesus Christ might be given to those who believe.
1 John 5:13 These things I have written to you who believe in the name of the Son of God, so that you may know that you have eternal life.
Now, please count the number of verses listed that mentions ANY BEHAVIOR OR LIFESTYLE, OR FOLLOWING. And then at least cite them.
And having been perfected, He became the author of eternal salvation to all who obey Him. Hebrews 5:9
After quoting these 21 verses, you really think that your single verse trumpts them all??
Quit dreaming. Realize that BECAUSE of the 21 verses listed, it is YOUR faulty understanding of Heb 5:9 that is the issue.
btw, you have harped in the past about the issue of believers taking the mark of the beast and going to hell. Even though there is NO evidence in Scripture that any believer will do that. The warning is for unbelievers who do that.
Rev 13:8 - All inhabitants of the earth will worship the beast—
all whose names have not been written in the Lamb’s book of life, the Lamb who was slain from the creation of the world.
Rev 17:8 sheds more light on who will take the mark of the beast:
The beast, which you saw, once was, now is not, and yet will come up out of the Abyss and go to its destruction.
The inhabitants of the earth whose names have not been written in the book of life from the creation of the world will be astonished when they see the beast, because it once was, now is not, and yet will come.
Notice the PAST TENSE (aorist) regarding WHEN names are written in the book of life: from the creation of the world.
So, God wrote ALL the names of those who would believe "from the creation of the world". And so all who NEVER believed were NOT WRITTEN in the book.
In Rev 13:8, it is those whose names "have not been written in the book of life" who will be those who take the mark of the beast.
So again, your opinion about believers taking the mark is unfounded. Totally.
