Contemporary voice of God

I intend to preach on Psalm 29 this coming Sunday.I still do not know how to use the verses.But I want to deal with the few thoughts below:

Human sufferings amid life's storms (3-8)
How can it be sure to hear God's voice ? (3-9)
How to respond to the call to worship ? (1-2)
The Lord's sovereignty amid life's chaos (10)
The given peace and strength of God's people (11)

The theme is about the voice of God but how can it be described well ?

God's voice in our chaotic & traumatic lives
God's voice in our worship & service
God's voice in our being His people
