A lot of people treat the matter of holiness as an expired topic or as an optional thing. This is not true. Holiness is a command from God. It is the nature of Saints, which is what we become when we get born again.
When Jesus Christ called His Disciples they were so committed that they left everything and followed. They were so dedicated and faithful to their call, except Judas Iscariot. We are also being enjoined today to follow Jesus Christ with the same level of faithfulness.
