“in the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight—”
Jesus reconciles us to God by the death of his physical body. The heretics against whom Paul is writing rejected the true humanity and deity of Christ. They taught that Jesus only suffered and died in appearance.
“in the body of His flesh through death”
The “body” here is the literal, physical body of Christ while he was on earth. There is no reconciliation without the physical death of Christ (Heb. 9:22). There can be no true death unless Jesus is truly human (Heb. 2:17; 10:10; I Pet. 2:24).
“to present you holy”
Jesus presents us positionally perfect before God by his death. The Lord Jesus will “present” us to God in a way that is acceptable to him. Our status before God will be eternal, infallible, unalterable. It will be the same status that Jesus holds before God. The word “holy” means set apart. Jesus sets us apart unto God as uniquely his.
“and blameless, “
Jesus will present us “blameless,” not flawless or sinless. No Christian is without fault in his experience. The term “blameless” means without spot (Eph. 1:4; 5:27; Phil 2:15; Jude 24). This is more than mere acquittal. No sin will ever be brought to the attention of God. God will not pick flaws and faults in us because of Christ.
“and above reproach in His sight—”
“Above reproach” is used five times in the New Testament Greek (I Cor. 1:8; I Tim. 3:10; Tit. 1:6-7). It is a legal term meaning unaccused and therefore free from all charges. Satan accuses Christians (Rev. 12:10) but Jesus is our Defense Attorney (I John 2:1) before the Father. Because of the death of Christ the believer is free from any charge that Satan may lay against him (Rom. 8:33). Satan cannot lay a charge against us. Even though we may deserve blame, Christ’s death makes us undeserving of blame.
Neither Satan nor God will impeach the believer because the believer is unimpeachable by the death of Christ. There is no possibility of a charge being laid against the Christian (I Cor. 1:8; I Tim. 3:10; Tit. 1:6-7).
“In His sight” means the penetrating gaze of God. Jesus is going to present us with the above three privileges to God. When we face God we will be set apart specially for God (holy), we will be without blame and no charge will be laid against us in his presence.
At the moment of trust in the blood of Christ to forgive us, our status and standing before God is perfect forever.
The perfect work of Jesus Christ is the genius of the gospel of grace. Religion does not do that for us. Automatically and instantaneously we are holy, without blame and without charge before God forever. At the moment we come to trust Christ as our Savior, God puts to our account all the exhaustless wealth of the Lord Jesus. We spend the rest of our Christian life learning of the wonder of what happened when we received Christ. We learn what we are worth. The split second we come to Christ God puts to our spiritual bank account all that Jesus is before him.
