How do we know God preserves His people?

The doctrine of preservation teaches that God actively keeps His chosen people from falling away. Jude 1:1 highlights this by stating that believers are 'preserved in Jesus Christ,' indicating that it is by God's power and purpose that they are kept secure. Romans 8:30 confirms that those whom God has predestined, He also calls, justifies, and eventually glorifies. This means that God's commitment to preserve His people is unwavering and eternal, emphasizing that our assurance in salvation is rooted not in our ability but in His sovereign grace and faithfulness.
