It’s funny how many people cherry pick verses out or Mark 16 to support their theology and ignore the rest.
Catholics do it as a proof text that water baptism is necessary for salvation but ignore the rest of the passage.
Pentecostals use it as a proof text for speaking in tongues, casting out demons, and laying hands on others for healing, but don’t practice the snake handling or drinking poison or use it so support water baptism.
People need to show some integrity when using Scripture. Either the whole passage applies or it doesn’t. You can’t pick and choose what you like about what Jesus says and discard the rest.
Amen - a little context goes a long way.
