Heretofore, I have written extensively on the extraordinary
depth and breadth of the atonement. What Christ accomplished for us on
the cross opened the door for God’s grace to become operative in our
lives.
At Calvary, Christ paid the penalty for our past sin and
terminated the law as a means of achieving righteousness. He settled
Satan’s claims against us, thus delivering us from Satan’s dominion.
Christ also put away sin, and in Him our carnal nature was executed.
To understand how this grace operates in our lives, we
must examine the difference between law and grace. The apostle Paul gave
us a key in 2 Corinthians 3 when he wrote: “Clearly you are an epistle
of Christ, ministered by us, written not with ink but by the Spirit of
the living God, not on tablets of stone but on tablets of flesh, that
is, of the heart. And we have such trust through Christ toward God.
“Not that we are sufficient of ourselves to think of
anything as being from ourselves, but our sufficiency is from God, who
also made us sufficient as ministers of the new covenant, not of the
letter but of the Spirit; for the letter kills, but the Spirit gives
life. But if the ministry of death, written and engraved on stones, was
glorious, so that the children of Israel could not look steadily at the
face of Moses because of the glory of his countenance, which glory was
passing away, how will the ministry of the Spirit not be more glorious?
“For if the ministry of condemnation had glory, the
ministry of righteousness exceeds much more in glory. For even what was
made glorious had no glory in this respect, because of the glory that
excels. For if what is passing away was glorious, what remains is much
more glorious. Therefore, since we have such hope, we use great boldness
of speech—unlike Moses, who put a veil over his face so that the
children of Israel could not look steadily at the end of what was
passing away” (vv. 3-13, NKJV).
Basically, the difference between the two covenants can be
summarized in this statement: Law commands the old man from the
outside; grace writes upon the heart of the new man from within.
Internal Transformation
Law is external; grace is internal. Law is outside
me—something I can point to and say, “That’s what I’ve got to do.” Grace
is inside me and changes me in such a way that it becomes natural for
me to act the way God wants.
In 2 Corinthians 3:18, Paul sums it up this way: “But we
all, with unveiled face, beholding as in a mirror the glory of the Lord,
are being transformed into the same image from glory to glory, just as
by the Spirit of the Lord.”
The veil Paul refers to that has been lifted from our
faces is our carnal understanding, from which we are delivered through
the cross (see Rom. 8:7; 1 Cor. 2:14; Gal. 5:24).
The “mirror” is God’s Word (James 1:23). When we look into
this mirror with faith, the Holy Spirit reveals to us the glory of
Christ and our inheritance in Him. As long as we continue looking in
this way, the Holy Spirit progressively changes us into the likeness of
what we see—”from glory to glory.” However, if we turn our eyes away
from the mirror of the Word—to ourselves, perhaps, and our own
ability—the Holy Spirit is no longer able to continue His transforming
work.
By His grace, God desires to produce within us the kind of
love that is not based on emotionalism or sentimentality. It is not
expressed primarily by religious clichés or religious activities.
Rather, it is a way of life, affecting every relationship and situation
in which we find ourselves.
To the Christians at Philippi, Paul wrote, “And this I
pray, that your love may abound still more and more in knowledge and all
discernment” (Phil. 1:9). This love continually leads us on into a
clearer and clearer perception of God’s will for every detail of our
lives.
There is always more to learn. As we see each detail
revealed in the mirror of the Word, the Holy Spirit applies it and works
it out experientially in our lives. Thus we are ever more and more
closely conformed to the pattern of Christ Himself (see Rom. 8:29). All
this is the result of a continuing inner work of the Holy Spirit, not an
external religious system of rules and regulations.
Another passage that points out the difference between the
old covenant of law and the new covenant of grace is Hebrews 8:10-12.
This passage is actually a quotation from Jeremiah 31:33-34: “For this
is the covenant that I will make with the house of Israel after those
days, says the Lord I will put My laws in their mind and write them on
their hearts; and I will be their God, and they shall be My people.
“None of them shall teach his neighbor, and none his
brother, saying, ‘Know the Lord,’ for all shall know Me, from the least
of them to the greatest of them. For I will be merciful to their
unrighteousness, and their sins and their lawless deeds I will remember
no more.”
In these verses, we see three ways in which the new
covenant differs from the old: (1) The Holy Spirit writes the laws of
God on our hearts and minds; (2) every believer can know God directly;
and (3) by one final sufficient offering, the very memory of our sins is
blotted out.
Grace is transmitted only by the working of the Holy
Spirit, who writes spiritual truths on our hearts. We do not read these
with our eyes, but they are absorbed inwardly and thus redirect the way
we live.
