There are times were you cannot see the deliverance, feel the praise and all hope is lost. It is worship that lifts us up.
There are times that God's still small voice speaks to us and says "I am here". The joy we feel causes us to worship in song.
There are times were you reflect on the goodness of Jesus and your soul cries out in PRAISE. That is a form of worship.
There are times were need to ask for help. Those desparate times call for worship.
