…He shall teach you all things, and bring all things to your remembrance… – John 14:26
The Holy Ghost is the great Teacher of the Father’s children. The Father begets us by His own will through the word of truth. Jesus Christ takes us into union with Himself, so that we become in a second sense the children of God. Then God the Holy Spirit breathes into us the “spirit of adoption, whereby we cry, Abba, Father.” Having given us that spirit of adoption, He trains us, becomes our great Educator, cleanses away our ignorance, and reveals one truth after another, until at last we comprehend with all the saints what are the heights, and depths, and lengths, and breadths, and know the love of Christ which passeth knowledge, and then the Spirit introduces the educated ones to the general assembly and church of the firstborn whose names are written in heaven. And here indeed we have a wide field spread before us, for He teaches to God’s people all that they do that is acceptable to the Father, and all that they know that is profitable to themselves.
Those first words which we ever used as Christians-“God be merciful to me a sinner,” were taught us by the Holy Spirit; and that song which we shall sing before the throne-“Unto Him that loved us, and washed us from our sins in His own blood, to Him be glory and dominion for ever and ever,” shall but be the ripe fruit of that same tree of knowledge of good and evil, which the Holy Spirit hath planted in the soil of our hearts. ~ C.H. Spurgeon
