New covenant believers receive such a fullness of the Spirit that sometimes we struggle to understand the conditions of believers in the old covenant. The Spirit withheld the fullness of His manifestation, and only some experienced a heightened revelation of His goodness. While this was more than sufficient for faith and worship, new covenant believers enjoy the astounding privilege of seeing the almighty God in the face of Jesus Christ. Jesus promised this blessing, and He fulfilled His promise at Pentecost, the unique event at which He poured out His Spirit in rivers of living water to His church.
