Israel future is waiting the blotting out of sins (Zechariah 13:1 KJV, Acts 3:19-21 KJV, 1 John 1:9 KJV) while the Body of Christ has already received the atonement (Romans 5:11 KJV)!
Here's what it really says and you ought to look at what it is you are actually citing. The first verse shows these Ephesians hath been quickened. It also shows what these Ephesians "WERE" in "time past". Then in spite of who they were, the "but now"/"but God" good news!
Ephesians 2:1 And you hath he quickened, who were dead in trespasses and sins;
Ephesians 2:2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
Ephesians 2:3 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
Ephesians 2:4 But God, who is rich in mercy, for his great love wherewith he loved us,
Ephesians 2:5 Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved
Ephesians 2:6 And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
Ephesians 2:7 That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.
Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Ephesians 2:9 Not of works, lest any man should boast.
Also: These Ephesians, like the rest of us today who have trusted the Lord believing the word of truth, the gospel of our salvation, are saved and sealed!
Ephesians 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
Ephesians 1:14 Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
