Thomas was present this time. The doors of his life were blown open and blown away. Notice Thomas' response. It is the most important response any believer, you and I, must ever make to Jesus. Those of who have never seen the physical, bodily form of Jesus are specially blessed by Jesus in these last words of John's Gospel.
Doors are important.
We need to think more of the problem with doors especially those doors we seem to consistently slam shut to Jesus. We have seen the Lord.
