After they prayed, the place where they were meeting was shaken. And they were all filled with the Holy Spirit and spoke the word of God boldly.
In this passage, Peter and other disciples and believers prayed to God to give them power to do His work. God sent his Holy Spirit. This is God living in me. This is the "advocate". If I lack boldness in life, in any situation, I need only look to God.
Holy One, when I lack the boldness to step out and do what I need to do, you are there to help. Help me to remember to turn to you always, in any and every situation. Amen
