How do we know salvation is guaranteed?

The assurance of salvation comes from God's unchangeable nature and His promises in Scripture. In Titus 3:5, we are reminded that we are saved not by our works but according to His mercies. God's grace is the foundation for our salvation, assuring us of eternal life. The consistent message throughout the Bible is that Christ was sent to save His people, and faith in Him is the means through which we receive this promise. Hence, our salvation does not hinge on our actions but solely on His faithfulness and mercy.
