How does God keep His people in salvation?

The assurance of salvation is rooted in God's ability to keep His people. 1 Peter 1:5 affirms that believers are kept by the power of God through faith unto salvation. This highlights that it is God's strength, not our own, that sustains us throughout our Christian walk. In Galatians 3, Paul questions whether believers can perfect their faith by their own efforts, stressing that it is God's grace that initiated and continues to uphold their salvation. The promise that God preserves His people until the final day encourages believers to trust fully in His power rather than their frailty, reaffirming that they are secure in Christ.
