Peter didn't know about the grace that was revealed to Paul...Paul didn't even know it for some time...And it was not taught at the beginning...
Doing works for repentance was prevalent...One couple was struck down dead because they with held information about some property...Another guy was told to sell everything that he had and give the money away...That doesn't happen under the gospel of grace by faith without works...
The couple who died lied to the Holy Spirit. Peter told them it was theirs to give, yet they lied. I see no command by Peter or any apostles for believers to sell all. All gave gladly.
I looked at Acts 4 & 5 and see no forced or commanded giving. People gave gladly. Perhaps you can point me to where Peter commanded someone to sell all.
