How do we know that God is able to save us?

The Apostle Paul declares in 2 Timothy 1:12, 'I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day.' This statement is rooted in the belief that Christ's work on the cross was sufficient to atone for our sins, abolishing death and bringing life and immortality to light through the gospel. Throughout the Scriptures, we see God's ability showcased in His power to save, redeem, and protect His people, emphasizing that our assurance of salvation is not based on our abilities or works but on His grace and power. Therefore, we can trust in His promises to keep all who have been called and saved by Him.
