As
Christians, we see the work of Christ on the cross as the only solution to the
problem of sin. We believe that Christ had to die in order for any sinners to
be saved. If God is completely sovereign over all things, however, why is
atonement necessary? Why could God not simply decide that He would forgive
somebody’s sins if He wanted?
The answer
to the question lies not in any limitation of God’s sovereign power but rather
in the essence of His character. The Bible teaches that God is sovereign (Ps.
135:6, Ps. 115:3, Is. 46:10). Nothing outside of God limits His power. He is,
however, self-limited. God cannot act contrary to His own nature or He would
cease to be the God revealed in His Word. The God of the Bible is perfect in
all of His attributes. He is perfectly holy, just, and true. His power is
therefore always consistent with those attributes, always consistent with who
He is, and there is no shadow of turning with Him (Jas. 1:17).
This idea
of divine self-limitation is not speculative theology, it is revealed in the
Bible in several places. It is perhaps most clear in the sixth chapter of
Hebrews where the writer explains that God could not swear by any name greater
than His own and that He cannot lie (Heb. 6:13-18). God does what He wills but
always does it in a way that is true to who He is. The Bible reveals that not
only is God sovereign, but He is also holy, righteous, and just (Is. 6:3, Is.
5:16, Job 37:23).
The
perfection of God makes the atonement necessary because God cannot be righteous
if He allows sin to go unpunished. Unlike Islam, which teaches that Allah can
simply use his sovereign power to disregard the sinfulness of those he chooses
and allow them into paradise, the Christian God does not undermine His own law
(thus denying His holy character) in order to do so. God is so holy that any
sin is a form of cosmic rebellion and if God did not punish such treason, His righteousness
and justice are compromised.
Suppose
that a man was a guilty of a brutal crime such as rape or murder and the
evidence of his guilt was unquestioned. Now, suppose that the man is brought
before a judge and despite the evidence, the judge decides to let him go. Not only
does the judge let him go, but gives him great honors and comforts. We all
agree this would be a great injustice and an unrighteous judgment. In the case
of salvation, the offensiveness of the crime is far worse and the mercy of the court
is a far more outrageous pardon.
This brings
us to one of the most fundamental theological problems for fallen humankind.
How is it possible for a holy, righteous God to save sinners without being
unjust? How can God fulfill the promises He has made to rebellious sinners
without compromising His own perfect character?
The answer
is the Gospel. The apostle Paul explains in the letter to the Romans:
“…all have sinned and fall short of
the glory of God, and are justified by his grace as a gift, through the
redemption that is in Christ Jesus, whom God put forward as a propitiation by
his blood, to be received by faith. This was to show God's righteousness,
because in his divine forbearance he had passed over former sins. It was to
show his righteousness at the present time, so that he might be just and the
justifier of the one who has faith in Jesus.” (Romans
3:23-26)
It was not
enough for sinners simply to be pardoned; they must be justified in a way that
is consistent with the righteousness of God. Since none are righteous and all
have sinned the solution had to come from God (Rom. 3:10, Eph. 2:4-5), while
the only appropriate representative to provide atonement had to be human (Rom. 5:15,
8:3-4). Therefore, God was pleased to offer salvation through faith in the
God-man Jesus Christ. Our sins, however, are not simply ignored.
Notice what
Paul says about this atoning sacrifice, “This
was to show God's righteousness, because in his divine forbearance he had
passed over former sins.” In order for the righteousness of God to remain
uncompromised, He had to judge sin. The suffering of Christ was a demonstration
of God’s holy wrath against sin so that no valid charge of injustice or
unrighteousness can be made. This is why Paul says Christ is a “propitiation”,
which means that He satisfies the wrath of God. All sin is therefore justly punished;
the question is if Jesus pays for our sin or if we will have to pay the penalty
ourselves.
Paul goes
on to say, “It was to show his
righteousness at the present time, so that he might be just and the justifier
of the one who has faith in Jesus.”
Because of the atoning work of Jesus Christ, God is both just and the
justifier of sinners. The cross is where God’s mercy and His justice come
together.
The
atonement is necessary in order to for a holy God to save sinners without
compromising His justice. He does not act contrary to His own nature. Salvation
is the result of God’s sovereignty, but not as an expression of brute power.
Instead, God’s sovereign work in the salvation of sinners is a demonstration of
His love and mercy.
The perfect
balance of power and love that is expressed in the cross of Jesus Christ is not
only a theological necessity but is a great comfort to believers. Since God’s
righteousness, grace, and power are all perfectly displayed in Christ, we can
look to the cross as assurance that God will keep His promises (Rom. 8:32).
Christians are not hoping on the whim of a changing God for their salvation. We
trust in the promises of a perfect, righteous, holy, and loving God who has
already demonstrated His commitment to those whom He loves.
