""They shall take up serpents; and if they drink any deadly thing"" ""Why don't you try it for yourself and find out for certain."" Obviously Mark 16:18 does not apply today yet Matt 24:13 does ? For believers today, why do some use the Gospels to teach how to enter eternal life yet they reject teachings like Mark 16:18 ? ** Confusion solution - ONLY Paul was given the UNIQUE role to teach how to enter eternal life to believers today & NOT the Gospels. It's called 2 Tim 2:15 .....rightly dividing the word of truth.” Correctly applying Scripture to the relevant audience & age.
