Revelation Knowledge

1 Timothy 6:20 (Amplified Bible) O Timothy, guard and keep the deposit entrusted [to you]! Turn away from the irreverent babble and godless chatter, with the vain and empty and worldly phrases, and the subtleties and the contradictions in what is falsely called knowledge and spiritual illumination.

God says in His word that His people are destroyed (perish) for lack of knowledge. The knowledge that God is speaking of is the knowledge of His Word - the Truth. This has to do with what God has said or spoken about a situation or circumstance. It is a spiritual truth or revelation that defies common sense or intellect. It is revelation knowledge. It's the kind of knowledge that says take two fish and five loaves and divide amongst over five thousand people and pick up twelve baskets of left-overs. There is also another kind of knowledge that is based on intellect, common sense and what can be seen, heard, tasted, smelled and touched. It's the kind of knowledge that says two fish and five loaves will only feed three to four people at best and then we'll all have to go to McDonald's afterwards. God says to oppose knowledge that goes against what He says in His word. It doesn't mean that you are to be careless or to not apply common sense to your daily lives, but it does say that regardless of what the facts may be, God's Word is the final authority and it is truth.
Have A Blessed Day
