Beware! All that glitters is not gold. For many are those that look good on the outside, but the inside reveals their true condition. Just as a cubic zirconium may appear to be a real diamond; upon closer inspection, you see what it truly is...an imitation. Its value is only a fraction of what the diamond’s is. In reality, it is a fake, a counterfeit.
So, too, you must be alert to what may look to be authentic, but in reality is meant only to deceive. For the enemy always offers counterfeits. Therefore, let My Word be the plumb line by which everything is measured, for it is truth. I am Truth. Know the truth and you will discern the false. For surely My people perish for lack of knowledge...
Amos 7:7 Amplified Bible (AMP)
Thus He showed me [a vision], and behold, the Lord was standing by a vertical wall with a plumb line in His hand [to determine if the wall was straight or if it needed to be destroyed].
Matthew 23:27-28 New International Version (NIV)
27 “Woe to you, teachers of the law and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of the bones of the dead and everything unclean. 28 In the same way, on the outside you appear to people as righteous but on the inside you are full of hypocrisy and wickedness.
Proverbs 29:18 Amplified Bible (AMP)
Where there is no vision [no revelation of God and His word], the people are unrestrained;
But happy and blessed is he who keeps the law [of God].
