Sound means the proper, appropriate, whole, right, and correct way of thinking. To have a sound mind, means to have the proper dissemination of information, which results in a right perspective. We know that the Word of God is sound and anything that does not fall in line with that is unsound point blank period. Satan loves to attack our sound mind with a spirit of fear, painting pictures that appear true, but aren’t. This is why exercising our God-given sound mind is so important.
God promises us three things that He has given us to combat the spirit of fear. These three things are power, love, and a sound mind. God has given us the power and the will to make the right decisions, to love, and have a sound mind. Yet, many of us do not maintain soundness of mind in our daily walks, but we allow our imagination to run to and fro flirting with whatever ideas we feel represent the moment that we are in.
If we are discouraged, we disseminate the message of defeat to ourselves. If we are upbeat, we disseminate the message of victory to ourselves. If we are angry, we disseminate the message of revenge, bitterness, or hate.
