Peter’s message presents the gospel, and God opens the eyes of 3000 people to repent of their sin and turn to Jesus. Now, those 3000 are looking to live out this new identity in Christ as this gospel begins to bear fruit in their lives.
What is the purpose of church? Is it that we have spotless theology? Is it that love our neighbors no matter what we believe? Or is it both?
God doesn’t ask us to understand his ways, but to trust his heart.
