Christianity's 3G

We have 3G and 4G in mobile technology. Now we are going for 5G. But in God's eternal plan for salvation, there is only 3G, which will sum up the whole of Christianity.

Guilt. Grace. Gratitude.

The terms "guilt, grace and gratitude" were taken from "The Good News We Almost Forgot" by Kevin DeYoung page 17.

The law revealed our guilt.
Why then was the law given? It was added because of transgressions until the Seed to whom the promise was made would come. The law was put into effect through angels by means of a mediator. (Galatians 3:19 HCSB)
For no one can ever be made right with God by doing what the law commands. The law simply shows us how sinful we are. (Romans 3:20 NLT)
So then, the law was our guardian until Christ came, in order that we might be justified by faith. (Galatians 3:24 ESV)

The penalty of the law was removed by grace.
But now we are released from the law, having died to that which held us captive, so that we serve in the new way of the Spirit and not in the old way of the written code. (Romans 7:6 ESV)
For sin will have no dominion over you, since you are not under law but under grace. (Romans 6:14 ESV)

We uphold the law out of gratitude.
Do we then nullify the Law through faith? May it never be! On the contrary, we establish the Law. (Romans 3:31 NASB)
For Christ is the end of the law for righteousness to everyone who believes. (Romans 10:4 ESV, NASB, HCSB)
