True Bible study really starts when you realize that much of what you were taught about the Bible might be incorrect.
Cognitive Dissonance is the concept that one holds two contradictory beliefs at the same time. A very simple example is John 3:16.
“For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life.”
As stated before most understand the word perish as “have everlasting life in torture“. The word means perish and that meaning is backed up in several other verses. Word studies can be helpful.
Don’t reject truth for church doctrine. Let the scriptures teach what they say.
2 Thessalonians 2:11 “For this cause God shall send them strong delusion, that they should believe a lie”.
