Old Testament God vs New Testament God

In our descriptions of God's character, we often find ourselves separating the God of the Old Testament and the God of the New Testament. We 'know' He is the same God, but then sentences like the following come out: 

- God was Justice before Christ and then He was Love
- God used to rule with the Law, now, He is gracious to us
- Grace wasn't present before Christ and was introduced through Christ

But that is all false. God, in the OT, was a gracious God, dispensing mercy, compassion and love since the creation of the world. He did not change His ways or introduce a new concept in Christ. He fulfilled it in Christ.

Here is the biblical proof of God the Father's link to Grace in the Old Testament:

• (G) describes God Ex 20:6, 34:6-7, Nu 14:18-19, Dt 4:31, 5:10, 7:9, Ne 9:32, 2Ch 30:9, Ps 37:25-26, 62:12, 77:8-9, 78:38, 86:15, 103:8, 106:45, 111:4, 112:4, 116:5, 145:8-9, Jr 9:23-24, Dn 9:9, Jl 2:13, Jnh 4:2, Mic 7:18-20, Na 1:3
• (G) is God's actions Ps 25:10, 145:17, Zc 4:7
• God's (G) for Israel remembered Ne 9:5-37
• (G) is God's longing Is 30:18, Ho 6:6 
• (G) is God's gift Ps 84:11, 2Co 9:8, Jm 1:17
• (G) is God’s throne He 4:16

It was Grace that saved Adam and Eve's life. Justice would have eradicated them for disobeying God's simple command in the Garden of Eden. It was Grace that appeared to Abraham. It was Grace that saved Noah. It was Grace that chose Israel and made Israel the nation it was. And the examples keep going throughout Old Testament history.

God never changed. Neither did His Grace.
