The Temple practices and rituals enabled God’s people to draw near to Him--
1. To find mercy and forgiveness and to be cleansed and refined
2. To receive life from Him
The mercy and forgiveness was found as the blood of a substitute animal was taken into the Holy of Holies by the high priest and sprinkled on the ‘mercy seat’ where the ‘Presence’ resided.
That this occurred on a place chosen by God which was once a threshing floor where grain was separated and purified or refined typifies the purifying and refining work of God in lives. John the Baptist said (of Jesus) to the Pharisees and Sadducees, “His winnowing fan is in His hand and He will thoroughly clean His threshing floor and gather His wheat” (Matthew 3:12)
The receiving of life from Him was typified by the presence of living (and life-giving) water at the Temple site, flowing from the Gihon Spring.
Yes, on a threshing floor and at a spring...two essential elements typifying the life of Jesus who takes away the sin of the world, refines those who come to Him--and, gives them (as He said) living water to drink!
