Acts 12:13 Peter knocked at the outer entrance, and a servant named Rhoda came to answer the door.
After the Lord released Peter from the prison he wondered around a bit before realising he should be with the people who were praying for him.
But when he went to the house where they were praying, a servant girl came to the door to see who was knocking – being so surprised to see Peter, whom they were praying for, she ran inside without letting him in!
Sometimes in our lives we get too caught up in the things we are doing for God that we lose sight of the simple things we should also be doing for Him. Open the door and invite people in!
