What does it mean that salvation is not by might nor power?

In Zechariah 4:6, the declaration 'Not by might nor by power, but by my Spirit' emphasizes that human effort, whether strength or wisdom, cannot effect salvation. This principle reveals that salvation is a work of the Holy Spirit, who regenerates and draws individuals to Christ. The reliance on God's Spirit underlines the total dependence on His grace, asserting that it is not our works, decisions, or abilities that can earn salvation. Instead, it is God, through His sovereignty, who brings about redemption according to His purpose and timing. Understanding this truth helps Christians to fully appreciate the grace that saves them, as it is entirely independent of human effort.
