How do we know that believers are preserved by God?

The doctrine of preservation asserts that once God has saved His people, they are secured in their salvation. Jude highlights this by stating the saints are 'preserved,' signifying a current and abiding state of being kept safe in Christ. This preservation is analogous to the way vegetables are canned; once processed, they remain sealed and free from spoiling. Furthermore, Romans teaches that believers, through Christ's resurrection, live unto God, indicating their life and preservation are rooted in Him. Their preservation is not dependent on their actions but on God's purpose and grace given before the world began.
