What is the explanation of John chapter 20 verse 19 to 23?

Answer 1

The bodily appearance of Christ when the disciples were hiding together for fear of the Jewish authorities is significant because in the account He demonstrated to them that He had arisen bodily. and that it was the same body that had been crucified, died, and entombed. Because it was such an amazing event outside of normality that Thomas who was absent, remained unbelieving - just as the other disciples had been previously - until he too saw Christ and touched his wounds just over a week later.
