What does it mean that the Spirit of God is poured out upon believers?

In Zechariah 12:10, the pouring out of the Spirit of grace indicates an abundance that God provides to His people. This is a promise of transformative power, enabling them to understand and embrace the grace offered through Christ. The Spirit comes not only to teach grace but also to instill in believers a spirit of supplication; it drives them to depend on God for mercy and strength. This outpouring signifies an intimate connection between God and His people, where the Spirit guides them into all truth and equips them for living out their faith.
