Silence is like a hole that we must constantly fill with shovels-full of words. It takes great effort for some of us to experience it. I think we often feed on the sound of our voice, feeling that, if we stop talking, people will stop listening (though many may have stopped listening paragraphs ago).
Imagine the silence of the women in Mark 16:8. What was going on in their minds? They had just seen an angel, heard his life-changing words, and received their mission-- “Go…tell…” No weeping or cheering, but being overwhelmed with reverential fear, just speechlessness!
Imagine seeing and hearing that for the first time. Has the message become too familiar to us for speechlessness?
