Yes, yes, yes, and yes -- but hell is never forever.  Rev. 20:12-14 shows that death and hell must both be emptied and destroyed so that the resurrections and final judgment can take place.  There is only finite punishment for finite sin.  God's love, justice, and mercy are all intact.

So why obey God now?  Because Jesus says that he shall reward us according to our works.  There are other glorious resurrections than the Celestial (e.g., the Terrestrial resurrection), and they offer their distinct and appropriate rewards in eternity.

We know from the Bible that "ghosts" do not exist since those who die go to heaven or hell depending on whether they placed their faith in Jesus Christ. However, there are demons that are perfectly capable of masquerading as deceased loved ones. In short, demons are real, but ghosts are not.

The Bible is very clear that no one can earn their way to heaven since good works do not pay for sins. See Gal. 2:16, Rom. 3:23-28, 4:4-5, Eph. 2:8-9, Tit. 3:5. The only way to heaven is by believing in Jesus for His free gift of eternal life. Jesus shed His blood on the cross as the full payment for our sins. He did all the work; all He requires of us is that we believe in Him. Once you believe in Jesus Christ to save you, you are secure forever!

Because we have all sinned against a perfectly holy and righteous God, we all deserve eternal separation from God in hell (Rom. 6:23). However, God loves us so much that He sent His only Son Jesus to die on the cross as our Substitute so we don't have to go to hell. Christ died for our sins, was buried, and rose from the grave three days later (1 Cor. 15:3-4). He gives eternal life freely to anyone who simply believes in Him for it. No one can be saved by doing good works. Salvation is by grace alone through faith alone in Christ alone (Eph. 2:8-9).

"Verily, verily, I say unto you, He that believeth on me hath everlasting life" (John 6:47).

No reason to believe in those things - because they don't exist.

"Many devils are on the earth today"

A total BULLSHYT Statement.  Just a goddam liar.

There's no legitimate proof for that whatsoever.

Many devils are on the earth today.  But they will be in the lake of fire for eternal torment.  And any person that refuses to believe in the Lord Jesus Christ, will also be in the lake of fire for eternal torment.  It is easy to avoid going there, because you need to believe in the Lord Jesus Christ, and then you are saved.  The Lord Jesus Christ is God, and He loves you.  Believing in the Lord Jesus Christ means being forgiven all sins past and future, and means going to heaven and not hell.  Death leads to immediate heaven or hell, and it is too late to be saved, after death.  All believers still sin.  See 1 John 1:8.  To be in heaven and not hell, believe in the Lord Jesus Christ, who is God and who died on the cross and shed His blood to pay for all of our sins in full, and who was buried, and who resurrected from the dead.  The only way to avoid hell is by believing in the Lord Jesus Christ, without adding any of your own works.  See Romans 4:5, 1 Corinthians 15:3-4, and John 3:16.

Humans are spirits housed in "tents". And humans can be both good and evil.

2 Corinthians 5:1 — For we know that when this earthly tent we live in is taken down (that is, when we die and leave this earthly body), we will have a house in heaven, an eternal body made for us by God himself and not by human hands.

Aside from that fact, there are no disembodied spirits walking the earth.

All the demons are in hell.

2 Peter 2:4 KJV — For God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment.
