Be not conformed to this world...today's church has compromised greatly...

But they have many rescuing devices (excuses) why they do so.

Telling the world that the world can come into a church and they will feel right at home is the formula of many churches today.  The ingredients are CCM, immodest apparel and a message of "greasy grace" that encourages the false notion that one can continue on in sin because grace minus repentance covers it all.  That is just naming a few...

The adversary hath spread out his hand upon all her pleasant things: for she hath seen that the heathen entered into her sanctuary, whom thou didst command that they should not enter into thy congregation. Lamentations 1:10

Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God. James 4:4

And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God. Romans 12:2
