HE ACTS LIKE HIMSELF
Mercy is an attribute of God, an infinite and inexhaustible energy within the divine nature that disposes God to be actively compassionate. Both the Old and the New Testaments proclaim the mercy of God, but the Old has more than four times as much to say about it as the New.
We should banish from our minds forever the common but erroneous notion that justice and judgment characterize the God of Israel, while mercy and grace belong to the Lord of the Church. Actually there is in principle no difference between the Old Testament and the New. In the New Testament Scriptures there is a fuller development of redemptive truth, but one God speaks in both dispensations, and what He speaks agrees with what He is. Wherever and whenever God appears to men, He acts like Himself. Whether in the Garden of Eden or the Garden of Gethsemane, God is merciful as well as just. He has always dealt in mercy with mankind and will always deal in justice when His mercy is despised. Thus He did in antediluvian times; thus when Christ walked among men; thus He is doing today and will continue always to do for no other reason than that He is God.
But because of his great love for us, God, who is rich in mercy, made us alive with Christ even when we were dead in transgressions—it is by grace you have been saved.
Wherever and whenever God appears to men, He acts like Himself.
You are God, and Your ways are perfect. You deal with us in mercy.
