Ok, then God chose to send people to hell for lying which is not justice.
You say you teach the Bible; so if you really know God's word, you already know God's word says
"liars" will go to the lake of fire and brimstone > Revelation 21:8. So, are you testing me to see if I also know what the Bible says? But this does not say that the lying all by itself will be the reason.
Also, there is His purpose for vessels of dishonor > Romans 9:21.
I now think of this > a person who trusts in and depends on lying is not trusting in Jesus. So, the person is rejecting God's own Son. And the person's horrible example of this can help others to also miss out. So, the liar is helping others to go to hell, also. When people do evil, they export this to others. So, this is part of what is wrong.
Plus, as I would suppose you know, there is no sin which is in isolation. Ones who do one thing have others they do, also. And what in the character makes this possible is what really matters. A person is being anti-Christ by how one's character is selfish. Plus, like I have offered, there is the evil spirit who is causing this > Ephesians 2:2 >
"the spirit who now works in the sons of disobedience." (in Ephesians 2:2)
This evil spirit is going to hell; so while a person is investing in Satanic activities of this evil spirit, the person is growing
"worse and worse" (in 2 Timothy 3:13) along with others, and then the person can go where the Satanic stuff of this is going > to the flaming sewer which burns with fire and brimstone.
So, a person's lies, by themselves, are not all there is to it.
So it is wise, then, not to allow this stuff in us; this is why, among other things we are told to put evil stuff away from us and get into how to love, instead >
"Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you." (Ephesians 4:31-32)
So, also . . . unforgiveness is anti- Jesus on the cross. But people in a Satanic spirit continue in what is not God's kind and tender way of forgiving. And so that stuff in them is going to the flaming sewer, and they are volunteering to keep it in them, of all things!! I would not volunteer for that job, but it appears many do.
And, by the way,
"evil speaking" includes calling God a murderer. Jesus is clear how Satan, not God,
"is a murderer" > in John 8:44. Plus, Satan is the one who is the father of lies, as the same scripture says . . . including how he has people lying by saying God is a murderer < that is not only lying but blasphemy and bearing false witness against God Himself. So, if people think our Father of Jesus is a murderer, they have God and Satan mixed up. So, if you know and teach God's word, you make sure you tell people this, and do not misrepresent God's word.
