How do we know God's kingdom will triumph?

Assurance of God's kingdom's triumph is rooted in His immutable nature and His righteous decrees. The imagery of the chariots in Zechariah illustrates how God's Spirit is actively working in the world, fulfilling His purposes. The sermon notes that even though worldly powers appear formidable, God assures His people that He is 'jealous for His kingdom,' working through His ministers and the preaching of the gospel to advance His agenda. Furthermore, in Romans 8:37, we see that believers are 'more than conquerors' through Him who loves us, emphasizing the invincibility of God's plan.
