Read | Romans 3:21-26
Romans 3 communicates the very heart of Scripture. Apart from the cross of Christ and His atoning death, no one can be declared righteous.
In other words, there is only one way to become a child of God—through the blood of the Savior (John 14:6). Good works and right living will not earn the Lord’s favor, because every person inevitably sins, and a sinner cannot enter the presence of holy God. The shedding of Christ’s blood on the world’s behalf made it possible for anyone to be cleansed of sin and have a relationship with the Creator. The only requirement is trusting Jesus as Savior.
For God to be just, He must remain true to His own principles. His holiness dictated that “the soul who sins will die” (Ezek. 18:4). The penalty for sin—namely, death—had to be paid in a way that was acceptable to God. He explained through Moses why a blood sacrifice was required: “For the life of the flesh is in the blood, and I have given it to you on the altar to make atonement for your souls; for it is the blood by reason of the life that makes atonement” (Lev. 17:11). A life must be given for a life to be spared.
On that basis, the heavenly Father provided a perfectly sinless sacrifice for all mankind. The only way God’s justice could be satisfied and His holiness could be maintained was for Jesus Christ to take our guilt and sin upon Himself and die in our place.
When we say that there is only one way to the Father, we mean that a person must believe Jesus Christ died as a perfect sacrifice. To trust in anything else is to ignore God’s holiness and the admonition of His Word (Acts 4:12).
