Why was it so crucial for the new apostle to have been with Jesus from the very beginning?
The early church leaders understood that for the message of the resurrection to be credible, the messengers had to be undeniable eyewitnesses. Peter emphasizes that the replacement for Judas wasn't just anyone, but someone who had been present and actively involved throughout Jesus' entire public ministry.
More Than Just Presence
This wasn't about passively observing. The phrase "went in and out among us" paints a picture of constant interaction and shared life. It implies a deep familiarity with Jesus' teachings, actions, and daily life, from His baptism and ministry start all the way through His ascension. This sustained companionship was the bedrock of their testimony.
