2 Corinthians 10:5 Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;
Matthew 6:34 "Take no thought..."
Matthew 6:25
When we use our imaginations to go beyond what is contained in scripture, it tends to lead us away from Truth. It causes us to build something from our own minds that is not a TRUTH from God. It is an idol in our mind, not a truth from God. It is there very thing that happened to Eve in the garden, even though God commanded only, "Thou shalt not eat..." Eve's thought process created in imagination that which she wished to possess...not of God...
Even David believed:
Psalm 27:13 I believe that I shall look upon the goodness of the Lord in the land of the living!
Jesus told us many times and many ways...The Kingdom of Heaven is INSIDE of us...yet we, by our own mind and imaginations look outside for it...building things that are outside of what scripture says...adding to it, if you will.
Luke 17:21 21 Neither shall they say, Lo here! or, lo there! for, behold,
the kingdom of God is within you.
Matthew 6:27 Which of you by taking thought can add one cubit unto his stature?
Isaiah 55:8 For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord.
9 For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.
John 18:36 Jesus answered, “My kingdom is not of this world. If my kingdom were of this world, my servants would have been fighting, that I might not be delivered over to the Jews. But my kingdom is not from the world.”
When we use our imaginations to picture/create something that is not a truth, that is not a spiritual thing to do...and causes us to believe something that is a lie, not Truth as from God. We tend to try and take a Truth received and build a golden cow or a city out of it...
