Why is the doctrine of salvation being from the Lord important for Christians?

Understanding that salvation is of the Lord is vital for Christians, as it instills confidence in the efficacy of Christ's work. Since salvation is rooted in God's grace and sovereignty, believers can rest assured that their standing before God does not depend on their own efforts or merit. In 1 Peter 1:5, Scripture states that we are kept by the power of God; this assurance allows believers to live in peace, knowing that they cannot lose their salvation as it is upheld by God's faithfulness. Moreover, acknowledging this truth encourages humility, reliance on God's grace, and a sense of gratitude for the profound gift of salvation that has been freely given to us.
