Acts 4:31

And when they prayed, the place was shaken where they were assembled together; and they were filled with the Holy Ghost, and they spake the word of God with boldness.

A time is coming when we will need to speak the word of God with boldness.  We will pray and move hearts and minds to the love of Jesus and being born again.  We have been put here on this earth to help others just like we have been helped.  God gave us the Holy Spirit to provide us with the strength and show us the way.
