How do we know that God's grace keeps us secure?

The doctrine of perseverance asserts that those who are truly saved will remain secure in God's grace. 1 Peter 1:5 states that we are kept by the power of God through faith unto salvation. This means that our standing before God is not dependent on our efforts but on Christ’s finished work. As believers, we are also reminded in Romans 8:33-34 that no charge can be brought against God's elect because it is God who justifies and Christ who intercedes for us. Understanding this gives us the assurance needed to remain steadfast and watchful as we await our Lord’s return.
