The period of the Law Covenant showed us mankind needs to change its mindset from self-justification efforts and understand the need for a Savior i.e. Christ. But how can Christ justify us when we still remain in our fallen flesh? When Christ taught us to pray for forgiveness, did he mention how often do we need that? If the Law showed us Christ's necessity, what happened to it after his arrival? Is it still in vogue?

Disregarding centuries of misuse of the English word, when we go to the original Greek, we see that repentance (Greek: metanoia) means 'a change of mind'. So what is it that we need to change our minds about? Why does the Bible say mankind is in an unjustified state? In Old Testament times, God gave Israel a set of rules called the Law Covenant. What was the deal there? How is that related to sin? And why did God provide the Law covenant (the Old Testament) if he knew there would be a New Testament?
