What is the cleansing of the sanctuary? Daniel, in the first 10 verses, is praying for understanding, wisdom, and discernment. The angel Gabriel comes back to Daniel to explain the vision, in particular, the 2300 days, taking into account that one prophetic day equals one literal year. Pastor Mark says this particular prophecy has had one of the biggest impacts on people’s faith, describing the exact time of Christ’s crucifixion.
