We must be filled with the Holy Spirit. This is no optional command of the Bible, it is absolutely necessary. Those earthly disciples could never have stood up under the persecution of the Jews and Romans had they not waited for Pentecost. Each of us needs our own personal Pentecost, the baptism of the Holy Spirit. We will never be able to stand in the tribulation without it.
Corrie Ten Boom, Letter from 1974
