The Seven Deadly Sins Teaching

I was thinking during Sunday School or on the month of April after Easter. Both the worship service and Sunday School should teach minors and the family of God about "The Seven Deadly Sins". The reason why I brought this up because minors and Christians can learn what sin is and also know how to repent. I was thinking churches should teach Christians and minors about "The Seven Deadly Sins" and repentance on the Sunday after Easter.

Here is the source that talks about "The Seven Deadly Sins":
