How do we know that salvation is entirely God's work?

The sermon emphasizes that salvation is not a cooperative effort between God and humanity; rather, it is wholly the work of God. In Ezekiel 37, God commands Ezekiel to prophesy to the dry bones, illustrating that it is God's voice alone that brings life. The bones do not respond of their own volition; instead, they are activated by God's decree. This biblical narrative reinforces the doctrine of total depravity — that humans, in their natural state, are spiritually dead and incapable of bringing themselves to life. Only God has the authority and power to save, as seen in His promise to breathe His Spirit into the bones, ensuring that they live. Hence, salvation is anchored in God's will and action, revealing the deep-rooted truth that He saves us in His timing and manner.
