The book of Mark was written to the Romans, he speaks of Jesus’ servanthood and he dives right into His ministry and record His miracles, as mark writes he focuses on His humility as a servant and doesn’t make mention of statements about kingly judgements. I found it interesting that in the great commission Mark records the signs that will follow those who believe: they will cast out demons, speak in tongues, take up serpent, and drink poison and not be hurt. The dispute over the last 12 verses is not a concern for me because God does not make mistakes and we have what we are supposed to have as Scripture.
