The Holy Spirit is described as the Comforter, like a mother would be a comforter to her child.  It is also said of the Spirit that He will lead us into all truth.  Who instructs children?  It is generally the mom, since she is with her kids most of the time. Who teaches baby Christians and weans them off of milk and into greater spiritual truths?  The Holy Spirit.
