But unless you repent, you too will all perish – This is a warning that Jesus gives his audience while teaching them about the issues of life. During the time of Christ, Jerusalem was an infamous city in which all kinds of wickedness were practised.
Forgiveness is one of the central themes in the Bible. Every born-again believer begins his walk with Christ from the day he receives forgiveness i.e. our life in Christ begins after we are forgiven by Him.
