A passage that has been misused - almost, at times, abused. (ab-used). This section in Acts has been used to support all sorts of ‘directed preaching’, such as you allude towards. Some have even tried to ‘emulate’ the ways of the ‘first’ church, and followed this practice.
The truth is much simpler, and makes far more sense. They had been warned that Jerusalem was to be annihilated. The key contextual aspect is that this (possession selling) only occurred in Jerusalem.
MARK 13:2 And Jesus answered and said to him, “Do you see these great buildings? Not one stone shall be left upon another, that shall not be thrown down.”
LUKE 21:20 But when you see Jerusalem surrounded by armies, then know that its desolation is near. 21 Then let those who are in Judea flee to the mountains, let those who are in the midst of her depart, and let not those who are in the country enter her.
So, why not sell up while ‘the going is good’ - and use the money effectively? They were not going to have their possessions much longer - they were set to lose everything.
I am not suggesting that there isn’t any alternative worthwhile message to be ‘read’ out of this story, because there is …
… As Jesus said, “By this shall all men know that ye are my disciples, if ye have love one to another” (John 13:35). To give of one’s own prosperity to help another is one of the greatest ways of showing that love (1 John 3:17).
It would appear that the believers still retained their homes by virtue of the fact that they met daily from house to house (Acts 2:46). But, it would also appear that this was not a long-term arrangement.
But, back to my point… There is no indication in Scripture that this type of communal living was repeated in other places where large numbers were converted to Christ. In fact, just a few years later, Paul took up a collection for the poor saints in Jerusalem (Romans 15:26), but note … this was not in Jerusalem.
