One of the unique jobs of the Holy Spirit in the life of a Christian is to continually guide them back to the truth of Christ.  In the midst of a chaotic and ever-changing world, this work is needed today as much as it was needed in the 1st century.  It's easy to place our hope in many other things than the solid ground of Christ and his work on our behalf.  How might the Holy Spirit bring us back to the bedrock truth of Christ, and Christ crucified?  And what difference would it make in our lives and our approach to our world?
