My dear friend in Christ, what goes on in your mind has a very great power to influence your future. The scripture says in Proverbs 4;23, "keep they heart with all diligence, for out of it are the issues of life". Also in proverbs 23;7 says " for as he thinketh in his heart so he is". From the foregoing it is apparent that our thoughts are very powerful creative force.
Look at Lucifer, he thought in his heart to be like God and immediately God reacted swiftly because God knows the power of thoughts and that with time his thoughts will become his experience.
Consider Job, a very successful man indeed but look at his secret thoughts of fear of calamity, God allowed the devil to make secret thought of Job his experience.
Beloved, remember that we are created in image and likeness of God and so whatever is conceivable is achievable. Fill yourself always with positive thoughts and eschew every negative thinking for it is a true saying that a man will become what he thinks most of the times.
In the morning when you wake up from sleep what goes on in your mind? Is it always fear of the unknown? is it worrying about how the day will be? or are you having a positive thought that your day would be great? when you are about going to bed, what are your last thoughts before you fall asleep?
Are they positive or negative? Note that your thoughts can make you or mar you. fear and worry are powerful weapons of the enemy and these weapons only operate in our minds .
So remove fear and worry not, have a positive thinking about life and about what you want to achieve and God, nature, and humans will cooperate to bring it it into reality, what you always think about.
