How do we know that our salvation is secure in Christ?

1 Peter 1:3-5 talks about our secure inheritance through the resurrection of Jesus Christ. It emphasizes that our salvation is not dependent on our performance but on Christ's finished work. His resurrection assures us that He has satisfied the demands of God’s justice for our sin. Romans 8:30 further confirms this; those whom He called, He also justified, and those He justified, He glorified. The promises of God are unfailing, and our salvation is kept by His power through faith until the end.
