Mark 1 study questions

Why are we told that John was clothed in camel’s hair with a leather belt and that he ate locusts and wild honey? (v 6)

What does it mean to be baptised with the Holy Spirit? (v 8)

Why are we told Jesus was with the wild animals? (v 13)

What did Jesus mean when he said "the time is fulfilled, the kingdom of heaven is at hand"? (v 15)

Why is the fever described as leaving Peter’s mother-in-law rather than her being healed of it? Likewise the leprosy later in the chapter (v 31 and v 42)

Why does Jesus ask so many in Mark to not tell anyone he has healed them? (v 44 the first occurrence)
