Worship is about ascribing worth to God in all that we do - both individually and corporately - such that God is glorified, the Church is edified, and the gospel is magnified for the world to see.
The Spirit of truth, under the authority of the Father and the Son, uniquely guided the disciples of Jesus Christ into all the truth, such that we now have the infallible truth of God in our Bibles. Rather than looking outside the Bible for truth, or seeking to alter the truth, we should look to the Spirit's guidance, that he might illuminate the glorious truth of Jesus Christ in our hearts and minds as we read his Word.
In John 15 and 16, we are warned of the inevitable hatred and persecution that accompanies the life of the Christian. In the midst of these warnings, however, Jesus points us to the Divine Helper who bears witness about Jesus both to us and through us, and who strengthens us to live all to the glory of God even when it hurts.
