How does God defend His church according to Scripture?

The defense of the church is a prominent theme in Scripture, notably illustrated in Zechariah 9:15, which asserts that the Lord of Hosts will defend His people. This role emphasizes God's sovereignty and power in safeguarding His church from both spiritual and earthly adversaries. God not only possesses the will to defend but has the ability to protect His people against all forms of opposition, just as He did historically with Israel. His defense involves not only external protection but also assurance that His people will not perish or falter in their faith, thereby illustrating the everlasting security believers find in Him.
