Empowered for Proclamation
Everything in chap. 1 is preparatory to the great outburst of the Spirit who poured upon the praying band of believers at Pentecost.
It’s a shame that the term “Pentecostal power” has for many people become more associated with speaking in tongues than with the harvest of world evangelization.
God’s Church is Empowered
Pentecost (also called the Festival of Weeks, Lv 23:15–16) commemorated the giving of the law on Mount Sinai and occurred fifty days after Passover and the Festival of Unleavened Bread. Jews either made pilgrimage to Jerusalem for Pentecost or remained there after Passover.
Someone who is already filled with or full of the Spirit can receive a further filling or enabling for a particular ministry (cf. Acts 4:31). So ‘our western logical concept that something which is full cannot be filled any further is misleading if applied to the Spirit.
When we look at the entire New Testament teaching on the Holy Spirit, we see the word baptism associated with initial conversion and the word filling with ministry. The first seems to happen once without repetition; the second occurs with frequency as believers allow God’s Spirit to produce powerful work through them.
