How do we know that God's promises are certain?

The certainty of God’s promises is rooted in His unchanging character and faithfulness. As expressed in Ezekiel 36:27, God assures His people that He will place His Spirit within them, empowering them to obey His commands. This dependence on God's initiative confirms that the transformation promised in Scripture does not rely on human will or effort but is fully accomplished by God's grace. Thus, believers can trust that they will walk in the Spirit and fulfill their divine calling, grounded in the assurance that God will not abandon His covenant people.
