“For John came to you to show you the way of righteousness, and you did not believe him, but the tax collectors and the prostitutes did. And even after you saw this, you did not repent and believe him.” -Matthew 21:32
John’s message is one of the shortest of all the Bible prophets. You can find the entire thing in Matthew 3:1-12, Mark 1:4-8, Luke 3:1-20, and John 1:15-35. According to Jesus, these 58 verses show us the way of righteousness.
I hope to look into this more in the future. For now, suffice it to say that repentance is vital, and it may mean more than you think.
