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?

Jesus Christ was the first to use the word 'Church' in the New Testament. Today, many think of churches as buildings. What is the Church actually, according to the Bible? The biblical root word for 'church' is the Greek ekklesia. What does that mean? How does the Bible describe the original churches? How does one become part of Jesus Christ’s Church? Are there any specific things that need to be done?
