But the Comforter, which is the Holy Ghost, whom the Father will send in My name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. – John 14:26

Let the Spirit of God be in the church, then there is power given to all her ministries; whether they be ministries of public testimony in the preaching of the word, or ministries of holy love amongst the brethren, or ministries of individual earnestness to the outside world, they will all be clothed with energy, in the fullness of the power of the Lord Jesus. Then her ordinances become truly profitable, then baptism is burial with the Lord, and the sacred supper is a feast of love; then the communion of the brethren in their solemn prayer and praise becomes deep and joyful, and their whole life and walk are bright with the glow of heaven. In the presence of the Lord the graces of the saints are developed; the church grows rich in all spiritual gifts; her warfare becomes victorious, and her continual worship sweet as the incense of the golden censor. What the moon is to the night, or the sun to the day, or the Nile to Egypt, or the dew to the tender herb, or the soul to the human frame, that is the presence of Jesus to His church. Give us the Spirit of God and we will ask no endowments from the State, nor sigh for the prestige of princely patronage. Endow us, O God, with the Holy Ghost, and we have all we need. The poverty of the members, their want of learning, their want of rank, all these shall be as nothing. The Holy Ghost can make amends for all deficiencies and clothe His poor and obscure people with an energy at which the world shall tremble. This made the apostolic church mighty; she had the Holy Ghost outpoured upon her.~ C.H. Spurgeon
