What role does preaching play in receiving the Holy Spirit?

Preaching is central to the Christian faith as it is the means through which Christ, our High Priest, sends the Holy Spirit to His people. As described in the sermon, the lamps in the tabernacle were maintained by Aaron and his sons, who represent the ministers of the Gospel. These ministers are tasked with preaching the Word to the congregation, allowing the Holy Spirit to fill their hearts with light. Christ promised the Holy Spirit to His people through the preaching of His Word, ensuring that believers are continually nourished and equipped for spiritual growth. Without faithful preaching that glorifies Christ, believers would lack the necessary oil to keep their spiritual lamps burning.
