I nick this wonderful post from Helen Rosenthal’s blog Reflections of an RSCJ.

When we pray, the door is always open. We are invited to enter and just be at home with the Lord. Sometimes this seems too good to be true. We want to believe it; we say we do, but we often wait at the threshold, timid and even fearful. We only need to look up and see that the door is open for us and the one who loves us is inside. He hears our prayer and opens the door even before we knock. The door will lead us into His Heart. Have confidence and courage and go forward. I think I often hesitate, feel unworthy, and yet I know from experience that I need just to go through the door of prayer and I can enter His Heart.
