"The tragedy is that many who have received the new birth continue to operate according to the same principle as the world. They have been born again to be citizens of Zion, but they are continuing to dwell in Babylon."

Is not this tragedy actually pictured in the beast that comes up out of the sea that had a deadly or death wound that was healed. This is also witnessed in other places by the Word revealed to us such as these following examples:
When Paul warns those after beginning by the Spirit but returning to the work of the flesh in Galatians.

The abomination that produces desolation setting itself up in the temple(house) of God is man living and in control by his own carnal thinking. The daily sacrifice dying daily to the old man that Paul taught is little known today. Presenting ourselves to God and not being conformed to this world but being transformed (translated)by the renewing of the mind is a mystery for most all who stay in Babylon.

1Ti 1:5 Now the goal of the commandment is love out of a pure heart, from a good conscience, and from sincere faith, from which some, having strayed, have turned aside to futile talk, desiring to be teachers of the law, not understanding either what they say or what they affirm.

Heb 13:10-16 We have an altar, whereof they have no right to eat that serve the tabernacle.
For the bodies of those beasts whose blood is brought into the holy place by the high priest as an offering for sin, are burned without the camp.
Wherefore Jesus also, that he might sanctify the people through his own blood, suffered without the gate.
Let us therefore go forth unto him without the camp, bearing his reproach.
For we have not here an abiding city, but we seek after the city which is to come.
Through him then let us offer up a sacrifice of praise to God continually, that is, the fruit of lips which make confession to his name. But to do good and to communicate forget not: for with such sacrifices God is well pleased.

I would like to share that we do not despise the small things. Do not look for the big and loud but pay close attention to the still & small things that many count as nothing. Oh how blind man is that walks by sight when faith is absent. One can see an earthquake and a fire but not a small voice.

1Ki 19:12 and after the earthquake a fire; but Jehovah was not in the fire: and after the fire a still small voice.

Heb 6:7-10 For the land which hath drunk the rain that cometh oft upon it, and bringeth forth herbs meet for them for whose sake it is also tilled, receiveth blessing from God: but if it beareth thorns and thistles, it is rejected and nigh unto a curse; whose end is to be burned.
But, beloved, we are persuaded better things of you, and things that accompany salvation, though we thus speak: for God is not unrighteous to forget your work and the love which ye showed toward his name, in that ye ministered unto the saints, and still do minister.
