How? Is it a sensation a magical one?
No, but it is supernatural. How can I explain it to you if you have not experienced it. It is the same experience that Paul speaks of when understanding is given to the Scriptures:
1 Corinthians 2:14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
--An unsaved man has a hard time understanding the basic truths of the Bible, even if he is well read. He may be a scholar. But he doesn't have a grasp on the basic truths of Scripture for a good reason.
1 Corinthians 2:11-13 For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.
--The Spirit of God is given to every believer. Every believer is able to understand spiritual things (like the Bible), because he has the Spirit of God.
12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
--The unsaved man has the spirit of the world; the believer has the Spirit which is of God. Therefore he is able to know the things that are freely given to us of God. One of those things is eternal life--a free gift of God.
13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
--Paul didn't speak with man's wisdom though he was very educated. He spoke as the Holy Spirit taught him, and led him. He compared spiritual things with spiritual things which is the same as comparing Scripture with Scripture. Note the many that would rather compare ECF and history to what they consider truth. This is not what Paul did. He relied on the Spirit of truth, and the Scripture.
You've only quoted that He give life but you don't explained the requirements or contract where he guarantees such a thing.
I only quoted one verse (John 10:27) for brevity's sake. I could quote dozens of others if you would like. If you want more say so, and I will give you others such as John 5:24; 1John 5:11-13 as well.
The guarantee comes from believing on Christ and his sacrificial work.
"Believe on the Lord Jesus Christ and thou shalt be save."
Acts 10:43 To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.
John 3:36 He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
1 Cor 15 has two problems. 1) In it Paul doesn't explain his gospel presented in the passage
He does. It is clearly presented in verses 1-4, one of the clearest presentations of the gospel in the Bible.
and 2)the guarantee is the resurrection of Jesus. You didn't see Jesus raise from the dead you're only taking his word for it.
I didn't see Queen Victoria, Hitler, or even Nero. But I know they existed. I know they existed because of faith. Faith relies on the witness of others. The witness of history tells me they existed though I never saw them. The resurrection is one of the most verifiable facts of history. It is verified by more than 500 witnesses. Can I go back in history and call more than 500 witnesses all liars? I don't think so.
1 Corinthians 15:6 After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.
this acutally works. In that your experience validates that what you believe is the truth. However, I don't believe in Mediums that they have any power but they can claim the same types of things.
I don't believe in mediums either. I believe in prayer.
John 16:24 Hitherto have ye asked nothing in my name: ask, and ye shall receive, that your joy may be full.
--That is what Jesus said to his disciples, and the promise is applicable to us today. Jesus is not a medium. He is risen from the dead and alive today. You can check his grave. He is not there. Christ is the object of my faith, the object of my prayers. He is risen from the dead. He is not a medium. He is God Almighty, the Creator of the universe.
Remember I'm asking questions that are in no way meant to be an affront to you or personal. In otherwords I don't believe you are deluded but it is the natural question. And these questions and statements are the natural one. As far as God did you see him to verify that he said those things recorded in the bible? Or was like the mormons say a burning in the bussom?
Read Hebrews 1:1,2
Hebrews 1:1-2 God, who at sundry times and in divers manners spake in time past unto the fathers by the prophets,
2 Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;
--In the OT God spoke to His prophets through an audible voice, through visions, through theophanies, etc. But he doesn't speak that way in this time. In this age he speaks through His Son. His Son is revealed to us through His Word. That is where we will find the Lord. He is revealed to us through His Spirit in the Word of God.
Read 2Pet.1:16 to the end of the chapter. In verses 16 to 18 Peter describes the most incredible experience that any man alive could ever have. He experienced the transfiguration of Christ. He saw Christ in all his glory and Elijah and Moses standing with him. Who wouldn't want to see and experience such a sight as this:
2 Peter 1:16-18 For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty. For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased. And this voice which came from heaven we heard, when we were with him in the holy mount.
Then what does he say:
2 Peter 1:19 We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts:
--We have a more sure word of prophecy.
Better than experience, better than the greatest experiences you may ever have is the sure word of God, the Bible that you hold in your hand is certain, sure. You can rest your faith on that, far more than you can rest your faith on experience.
All other books, such as the Book of Mormon, have contradictions. The Bible has no contradiction that doesn't have an answer for it. In other words there are "seemingly" contradictions to some. But they aren't. There is an answer. There are no contradictions in the Bible. I rest my case on the Word of God.
Jesus said: "I am the way the truth and the life; no man comes unto the Father but by me.
--Either what he spoke was true and he is the only way to heaven, or he is the biggest liar, fake and deceiver that ever walked the face of the earth. Who is Jesus Christ? That is the question you must answer.
