Acts 4:29-33:

And now, Lord, behold their threatenings: and grant unto thy servants, that with all boldness they may speak thy word,
By stretching forth thine hand to heal; and that signs and wonders may be done by the name of thy holy child Jesus.
And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness.
And the multitude of them that believed were of one heart and of one soul: neither said any of them that ought [any] of the things which he possessed was his own; but they had all things common.
And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all.

Notes on Acts 4:29-33:

It is Scriptural to pray for boldness and to pray for signs and wonders!  You should do it!  Note that the emphasis here was more on the boldness than the signs.  The miracles accompanied the bold preaching of the Word and the disciples prayed for both.  The two go together.  Don’t just pray for miracles; pray for boldness to preach the Word.  Power will follow your boldness, too.  We are talking about a Spirit-given boldness, not a natural boldness that comes from being an energetic public speaker.  You can be “naturally” bold and have no signs follow you.  You want to be supernaturally bold.

The disciples were not re-baptized in the Holy Spirit; they were refilled with the Holy Spirit.  This shows that there is one “baptism” with the Spirit but many “fillings” with the Spirit.  Paul exhorted the Ephesians, who already would have known about the Spirit baptism since Acts 19:1-6, to be filled with the Spirit instead of filled with booze (Ephesians 5:18).  I believe that this refers to having the Holy Spirit who is already in you rise up.

It would be scriptural to see a building shake today when such united prayer is offered.  How many believers would be a quorum for such action?  Two, based on the passage below that contains the account of the original Jailhouse Rock.

Acts 16:25-26:
And at midnight Paul and Silas prayed, and sang praises to God: and the prisoners heard them.
And suddenly there was a great earthquake, so that the foundations of the prison were shaken: and immediately all the doors were opened, and every one’s bands were loosed.

This is not a “claimable” event; no Scripture promises you that you can have a building shake every time there is united prayer or praise, but it IS possible as the Lord wills.

While these disciples pooled their resources, that was never a requirement – it was just something they wanted to do.  Peter’s response to Ananias that the land and then the money he got for it were his own (Acts 5:4) proves that God has never enforced any form of “Biblical Communism.”
