Isaiah teaches us that the sacrifice for sin was for all of us. John tells us that it is for the whole world. Therefore, we see that as by nature we are all included under sin, so also, by the sacrifice of Jesus Christ, the righteous, this sin debt was paid for all. He gave His life by the shedding of His blood. As there could be no remission for sins without the shedding of blood, so His life s blood was the ransom price by which we are redeemed.
Redemption means to buy back from under the penalty of law.
Jesus Christ died in our stead, and the price of His blood was acceptable to God, the Father. So, when the apostle saw Him transfigured in the state of His glory, as He is today, after having triumphed over death, hell and the grave, the voice of the Father was heard to say, This is my beloved Son in whom I am well pleased, here ye him. God accepted the price of our redemption, and salvation was made possible and free to every person who will accept it from Jesus Christ. There are always conditions which produce a birth. The new birth is no exception to the rule that conditions determine the birth.
