Following Jesus means being open to and led by his Spirit. This book explores the meaning of this phrase by looking at the larger picture of why God entered our world and became one of us in the first place. It hinges on one fundamental insight. If the mystery of the Incarnation marks the beginning of a renewed friendship between God and man, then the sending of his Spirit reveals an even deeper way for the two of them to relate. Because of the Spirit, God is now be able to dwell within the human heart throughout the corridors of history.
