Trina,
When you have an aha moment, those are called epiphanies...divine messages. How to tell if they are from God....
The devil only wants to kill, steal and destroy. His messages will not result in peace, comfort, happiness, thanksgiving, joy, or any other fruit of the spirit.
God's messages will be centered on Him, on Jesus, on love, on the fruit of the spirit, on helping others. God's messages will not be "self"-centered. He will of course send messages to minister to you but they will not be spot lighting you they will be spot lighting Him and what He wants to do through you.
What you need to do when those feelings of fear and doubt come is fight. The bible says to take our thoughts captive and to pull down every thought and that is contrary to the Word and our knowledge of God.
The bible says to think on these things (and only these things):
6Be ANXIOUS for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
7And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
8Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
When fear and doubt try to creep in recognize that those thoughts are not from God because He hasn't given us a spirit of fear. Then recognize that He has commanded us to take those thoughts captive and to toss them out of our heads. Just because a person knocks on your door does not mean you have to let them in your house and just because satan drops a thought of worry and doubt in your mind does not mean that you have to let it stay..kick it out.
If you have to cast down thoughts fifty times a day do it. I did this for about two weeks VERY CONSISTENTLY and after that I didn't have the problem with those thoughts anymore. They come once in a while now but they are a lot easier for me to dismiss and I do it almost automatically now. BUT Once you cast down the thought replace it with the truth. Get out a list of bible scriptures that conflict doubt and have them available to replace negative thoughts with. Meditate on your list of scriptures every time that you start to worry and you will win!
Love,
Mia
