Colossians 1:20 And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven.
‘Having made peace through the blood of his cross.’ Justification is used for the final settlement between people (Job 11:2; 13:18; 27:5; 32:2; 33:32; Pro. 17:15; Luke 10:29; 16:15); of people clearing God of all wrong (Ps. 51:4; Luke 7:29; Rom. 3:26); and of people justifying themselves of all guilt (Jer. 3:11; Ezek. 16:51-52; Job 9:20; 13:18; 32:2; Luke 16:15). Thus, the meaning is clear – to declare not guilty. The justification of man by God simply means that God washes, sanctifies the believer, and declares him no longer guilty (1Cor. 6:9-11; 2Cor. 5:17-18; Acts 13:38-39). God cannot declare one not guilty before he is cleansed from all sin and made holy by the blood of Christ. Sanctification makes the sinner not guilty; justification declares him not guilty. This alone is the function of the blood of Christ: cleaning from sin which makes us holy. Pleading the blood of Christ over us for protection is unscriptural and wrong for protection from God comes from being reconciled with the Father who is the one we have to “dwell with” and “abide under” as commanded in Psalm 91.
‘To reconcile all things unto himself.’ [Greek: katallasso] change from enmity to friendship, reconcile (Rom. 5:10; 1Cor. 7:11; 2Cor. 5:18-20). God was in Christ, reconciling people to Himself. He does not impute sin to those who have confessed and are reconciled to Him (Rom. 4:7-8). God has committed to the reconciled [us] the word of reconciliation. God has made the reconciled ambassadors for Christ reconciling others by their example (2Cor. 5:20; Rom. 5:10). God made Christ a sin-offering, so that man might become righteous (2Cor. 5:21).
‘I say, whether they be things in earth, or things in heaven.’ This will be completed in the Millennium (1Cor. 15:24-28; Eph. 1:10; Rev. 20:1-15).
