What does the Bible say about God's sovereignty in building His church?

In Zechariah 4:6-7, the Lord proclaims to Zerubbabel that the restoration of His temple will not happen through human strength but through divine empowerment. This reveals God’s sovereignty, asserting that He is ultimately in control, even over the hearts of kings. The underlying message is clear: The construction of God's spiritual temple, including building up His church, is dependent on God's work through His Spirit, rather than human effort. This principle resonates throughout Scripture, underscoring that while believers are called to be active participants, the ultimate success of the ministry rests in God's hands, affirming the historic Reformed belief in sovereign grace.
