2 Thessalonians 2:7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.

What is the mystery of iniquity?

I believe the mystery of iniquity is the driving force of sin rise in this end time.

The mystery of iniquity is the desire by humans to replace God, it is the desire to replace the divine with the earthly.

When moses went up to the mount Sinai for 40 days the Israelites wanted to a replacement of Jehovah they wanted what they could see and touch in other words they wanted practicality instead of faith.
Also during the days of eli the israelities wanted a human king who they can see, who will go with them into battle like other human kings not the invisible king that cannot be touched or seen by mortals.
It is all about practicality, the mystery of iniquity seeks to replace God with something practical, God's instructions are considered archaic(impractical) and are either modified or discarded totally instead new ideology (gods) are embraced because they sound cool, non extremist, and inline with the times.

The mystery of iniquity is spiritual lawlessness that reigns supreme in this latter days.

In the church newer doctrines or modified biblical doctrines that are so called refined due to better understanding replace the doctrines and teachings of Christ in the early church, many now know more than Jesus and the 12 apostles.

The mystery of iniquity expresses itself in the worship of men in the name of anointing, denomination,buildings eloquence, achievements, money, fame, attractiveness etc


The mystery of iniquity replaces God with self, many believe and do whatever comes out of their mind, they dont care about what God says.

The mystery of iniquity expresses itself in people attending and heaping teachers who only teaches what they like, such false teachers are honored, glorified and praised.
People only attend churches whose teachings agrees with their mindset, any preacher, prophet, teacher, pastor G.O that teaches what aligns with their belief is the true man of God and the truth to them, it is not about what God says even if it is better. They know that God does not support them but they are looking of a way to maneuver it either by looking for more insight or better understanding or a so called spiritual depth.

The mystery of iniquity is already at work in the church, schools, industries, government social gatherings and families.
It is the replacement of God with something else, human ideas instead of God's word, God is considered as biased, and rigid. Truth is cast to the ground, individuals now have their own truth according to what suit them, spinning narratives to drive home their desires.
Lawlessness!, lawlessness!! lawlessness!!!

The antichrist is a replacement of Jesus, since they do not like to retain God he will give them their desire.

Many talk about Jesus, but the Jesus they believe in is not the Jesus of the bible. The Jesus of the bible came to save men from sin and return them to hos father and God but the Jesus many believe in is the Jesus that agrees to whatever they do whatever they like, hence many say the God in the old testament is not the same as the new testament.

In summary, the mystery of iniquity is the desire to replace God with something else.
Therefore, all saints of God should keep themselves from idolatry, which is replacing God with something else.
God 's word is supreme, unchanging, true full of wisdom and sure.
His word is just as good as himself, as paul said, who can separate us from the love of God in christ?
1 John 5:21
Little children, keep yourselves from idols. Amen.

Romans 8:35-39 Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or unclothedness, or peril, or sword?

As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter.

Nay, in all these things we are more than conquerors through him that loved us.

For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,

Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.

For you to know the Biblical understanding of the term INIQUITY you must have fully grasped what EQUITY means!

Perhaps let's try the definition of both from the English Dictionary

EQUITY

©Fairness, impartiality, or justice as determined in light of "natural law" or "natural right".
©Within many types of society, the jurisdictional principle from which a court of law or other similar legal body derives a certain extra-statutory discretion and is thereby empowered to decide legal matters and to provide legal relief apart from, though not in violation of, the prevailing legal code; in some cases, a court "sitting in equity" may provide relief to a complainant should the code be found either inapplicable or insufficient to do so.
©Within the context of the English common law system, equity is the body of law which was developed in the English Court of chancery and which is now administered alongside the common law.


INIQUITY

©Deviation from what is right; gross injustice, sin, wickedness.

©An act of great injustice or unfairness; a sinful or wicked act; an unconscionable deed.

Having known this one can now examine what the founder of Christianity (Jesus) meant by "Iniquity" among those claiming they're his followers! Matthew 7:23

Jesus is Lord and saviour

Tr

Father God your name be glorified
