John 12:34 The people answered Him, “We have heard from the law that the Christ remains forever; and how can You say, ‘The Son of Man must be lifted up’? Who is this Son of Man?”
It is right to question things! This does not mean we should argue about anything and everything; we have teachers whom we should believe.
God wants us to be able to understand enough about Him so we can get to know Him and trust in Him as much as any people throughout history.
But just because someone says something does not mean you should just accept things. We need to compare what we are told with the scriptures to make sure we are being told God’s truth and not man’s own story.
