1 John 1: 6. If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:

Any body want to be like Jesus?  To be a Christian is to be "Christ-like".  We hear all kinds of things that will make us "Christ-like".  Our faith should allow us to do miracles!  We should speak things that aren't as though they are!  Our words will make it so!  Name it and claim it stuff that the bible really doesn't teach.  The "Prosperity" promise that God will make you rich if you will only believe enough to send what-ever ministry your last $100.00

Want to really be like Jesus?  Want to really be a "Christian" and not a deceived sheep?  Want to know how to tell the difference?

Christians seem to believe that they can keep a little shadow experience hidden in their lives and still be OK.  The bible doesn't show that to be true.  If you really want to be a true believer...get rid of all your darkness, shadows and shameful practices.  If you are doing something you would hate to be exposed...it is spiritually dark, and a trap, and keeps you from being totally in the light!  Repent!

Jesus never told a lie!  Jesus never did anything he was ashamed of!  Jesus didn't live two lives, one for the public and one for private.  He was the same always.  Honest.  Above reproach.  Blasting away darkness with the light!  Want to be like that?  That's what it takes!

Here are a few scriptures that shed some light.

John 1
 1.  In the beginning was the Word, and the Word was with God, and the Word was God.
 2.  The same was in the beginning with God.
 3.  All things were made by him; and without him was not any thing made that was made.
 4.  In him was life; and the life was the light of men.
 5.  And the light shineth in darkness; and the darkness comprehended it not.

John 3:
 19.  And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
 20.  For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
 21.  But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.

John 8:
12.  Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.

Acts 26:
18.  To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me.

2 Cor. 6:
14.  Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?

Also:
Psm 51:
 6.  Behold, thou desirest truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.
17.  The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise.

What makes a "Christian" Christ-like is the love for truth.  Jesus IS truth.  If you love a lie...any lie, the truth is not in you!  Many are "moon" Christians, with light shining on the front, but still having a dark side.  In Jesus there is no darkness at all.  With Jesus truly on the inside, the light permeates completely from the inside out, leaving no potential for shadowy secrets.

Did the apostle Paul keep secrets? Yes!
1 Corinthians 3
 1.  And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ.
 2.  I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able.

But his secret was not hiding darkness, but light that couldn't be comprehended yet.

Are you hiding any dark secrets?  Dark practices?  Walk away from them...repent.  Repentance isn't just having Godly sorrow, it is turning away from the darkness and turning toward the light!  Don't worry that you will be accused of being "self-righteous" by those loving darkness.  You know you have no righteousness in your self.  You are a stinking sinner that is walking away from darkness and toward the light.  "Moon" Christians are like lobsters, if they see one climbing up and over, they will try their best to drag the escapee back into the bucket.

And finally:
Matthew 7:
 13.  Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat:
 14.  Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
 15.  Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
 16.  Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
 17.  Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
