Why is God's grace considered essential in salvation?

In Ephesians 2:8-9, Paul states, "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast." This highlights that salvation is entirely a work of God's grace, independent of human effort. Understanding grace helps believers to grasp the fullness of their salvation, recognizing that it is through God’s unmerited favor that they are saved. Emphasizing grace encourages a humble reliance on God’s work in our lives, instilling gratitude and a desire to live for His glory.
