What does being 'kept by the power of God' mean?

The phrase 'kept by the power of God' indicates that our salvation is continually sustained by God’s sovereign power and grace. This concept is found in 1 Peter 1:5, where Peter reassures believers that, despite trials, their inheritance and salvation are guarded by God's power through faith. This preservation is vital for ensuring that believers remain steadfast in their faith and are ultimately brought to glory. Thus, our security in salvation does not rest on our ability to maintain our faith but on God's unwavering commitment to uphold His promises and protect His people, reinforcing the assurance that, once saved, they are secure in Christ.
