“And they were all filled with the Holy Spirit” (Acts 2:4).
“And when they had prayed, the place in which they were gathered together was shaken, and they were all filled with the Holy Spirit and continued to speak the word of God with boldness” (Acts 4:31).
“For in one Spirit we were all baptized into one body—Jews or Greeks, slaves or free—and all were made to drink of one Spirit” (1 Corinthians 12:13).
God’s plan is that all the body of Christ be filled with the Spirit and equipped “for the work of ministry” (Ephesians 4:12), not just a few. What a powerful expansion of the gospel would take place in our day like it did in Acts if we believed and taught this truth! There would be an automatic change of focus from internal self-centeredness to an outward looking church that thinks about the nations (ethnos, people groups) who have never heard the gospel. The unbeliever who comes into the church would fall on his face and “declare that God is really among you” (1 Corinthians 14:24-25). Obedience to the Word of God would be compelled by the power of His Spirit, not demanded by leaders.
It is pointless for me to list all the changes that would take place. But allow me to add one more which we see in the reference above in Acts 4:31. In the face of opposition and persecution, they “continued to speak the word of God with boldness.” The day we live in requires this kind of Spirit given boldness that flows from the authority and sufficiency of God’s Word in us. God wants us to experience this filling, not just read and talk about it. It only requires a serious desire and yielded heart and mind on our part.
