If we look at the books of the New Testament (NT) we see a recurring theme. Avoid sin at all cost, and do good. This is a requirement for the believer. The NT books declare and teach what sin is. These books also declare that fruit has to be produced by the believer. The modern church teaches that this fruit consists of inviting people to church services. The NT declares that this fruit is a person’s goodness, righteousness, fairness, and justice. This fruit demonstrates holiness by the believer. The church today in the West teaches that a believer cannot be holy. Churches here teach that holiness is not about your behavior, that holiness is an abstract concept applied to you after you have said a prayer to God.
This teaching is clearly not correct when we read the NT. The believer has been moved from the power of darkness to light in the NT. They are no longer defenseless against sin. They have protection against temptations in Christ. A believer is to use the tools that Christ has given to them to increase their goodness and holiness. The reading of the Word to renew their mind, praying to call upon God and to hear from God, the accepting of the baptism of the Holy Spirit and with this acceptance the believer receives power to resist sin.
The idea of a believer needing to obtain holiness is also portrayed in the Old Testament within the statutes and rules given in the Law of Moses. The OT Israelites were to perform certain requirements such as washings, learning what was clean and unclean and abstaining from the religious activities and practices of other nations, sacrifices were to be continually made for their sins, etc. These were actions and requirements that had to be done and performed by the priesthood and the people.
The current teaching in the West undermines the importance and even the requirement of the believer to seek after righteousness.
