True worship is a response to what God has done. True worship can only come from a recognition of God's presence and character through an intimate encounter with a wholly other God. No matter how many songs we sing, how many people we convert, and no matter how long our prayers, if it isn't in reaction to a Divine God, it isn't worship.
True worship is impossible for us alone. Who among us has come to God where he dwells in Heaven? Rather, if not for the revelation of God himself to unto us, who could worship? But praise God that he has revealed the fullness of his glory to us through his Son, the word become flesh, Immanuel, God with us, crucified on the cross and displayed for all to see.
It is through radical encounters with His Holy Spirit that anyone can say they worship God. It is a direct response to the power of God. Let this crippled beggar be our model for true spiritual worship.
