Ephesians 2:8

A major passage for understanding God’s grace, i.e., his kindness, unmerited favor and forgiving love. you have been saved. “Saved” has a wide range of meanings. It includes salvation from God’s wrath, which we all had incurred by our sinfulness. The tense of the verb (also in v. 5) suggests a completed action with emphasis on its present effect. through faith. See Ro 3:21–31, which establishes the necessity of faith in Christ as the only means of being made right with God. not from yourselves. No human effort can contribute to our salvation; it is the gracious gift of God.
