When my family was young and I was a young father and pastor, finding a quiet time and place to study could be a challenge. As my children grew older, when I was in my small study at home, they understood I was at work on my messages for the church.
But it was different for the younger children, as my wife pointed out many times. They could burst into my little study anytime they wanted. Later, my church office staff learned that when my wife called, she had priority over who was in my office or what I was working on.
The Lord helped me see this is the access we have Him, even when we're older. We can burst into the Lord's presence whenever and whatever the need.
The door is never closed to the Father's presence for those of us who know Him as our Father. He always has time for us and gives us His full attention.
