“Christ as Mediator also entered the penal relation to the law, in order to pay the penalty in our stead. His passive obedience consisted in His paying the penalty of sin by His sufferings and death, and this discharging the debt of all His people. The sufferings on Christ, which have already been described, did not come upon Him accidentally, nor as the result of purely natural circumstances. They were judicially laid upon Him as our representative, and were therefore really penal sufferings. The redemptive value of these sufferings results from the following facts: They were borne by a divine person who, only in virtue of His deity, could bear the penalty through to the end and thus obtain freedom from it. In view of the infinite value of the person who undertook to pay the price and to bear the curse, they satisfied the justice of God essentially and intensively. They were strictly moral sufferings, because Christ took them upon Himself voluntarily, and was perfectly innocent and holy in bearing them. The passive obedience of Christ stands out prominently in such passages as the following: Isa. 53:6; Rom. 4:25; 1 Pet. 2:24, 3:18: 1 John 2:2, while His active obedience is taught in such passages as Matt. 3:15, 5:17-18; John 15:10; Gal. 4:4-5; Heb. 10:7-9, in connection with the passages which teach us that Christ is our righteousness, Rom. 10:4; 2 Cor. 5:21; Phil. 3:9; and that He secured for us eternal life, the adoption of sons, and an eternal inheritance, Gal. 3:13-14, 4:4-5; Eph. 1:3-12, 5:25-27.” (Berkhof, Systematic Theology, 381)
