Leviticus 19:1-2
And the Lord spake unto Moses, saying,
Speak unto all the congregation of the children of Israel, and say unto them, Ye shall be holy: for I the Lord your God am holy.
The basic requirement for life in the Kingdom of God is to possess personal holiness. God requires us as believers to be holy, there is no compromise. It is the most important requirement in order for you to destroy the works of darkness.
