What does Zechariah say about the role of the Holy Spirit in understanding the gospel?

In Zechariah 4, the absence of human dependence for the golden candlestick signifies that understanding the gospel is not achievable by human might but solely through the Spirit of God. Just as the lampstand in the temple consumed oil provided by the olive trees, believers require the Holy Spirit to illuminate their minds and hearts regarding the truths of the gospel. This illustrates the necessity of divine assistance in perceiving spiritual truths, without which, mankind remains in darkness and unable to grasp the significance of Christ and His work.
