The energy that created and maintains creation is a witness to the God from which it proceeds.  The acts of God in the lives of His people declare Him.  Jesus is the supreme revelation of God, validated by His resurrection.  God reveals Himself by His Spirit in prevenient grace.  All of these overtures of grace do not predestine nor force belief.  They are an invitation to embrace the One who has already embraced us.

“Simon Peter answered, ‘You are the Messiah, the Son of the living God.’  And Jesus answered him, ‘Blessed are you, Simon son of Jonah! For flesh and blood has not revealed this to you, but my Father in heaven.’” Matthew 16:16-17 (NRSV)
