When you believe something, it will affect your feelings. When you believe you are a failure, you will feel like one. When you believe you are a forgiven saint, you will feel like one.
The difference between a guilt-ridden Christian and a light-hearted and joyful Christian is often one simple thing… what they are thinking about. Guess who’s thinking about the sin, the guilt and the past? Now guess who’s thinking about how they have been washed clean and they are a new person in Christ Jesus?
Whatever you keep your mind on (think about often) will affect your whole being. Isaiah 26:3, “Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee.”
An exception to the rule: Evil spirits are known to directly affect our emotions, feelings, etc. King Saul was tormented with fear and depression directly. However, evil spirits often use our thoughts to access our feelings, and this is done through the creation of strongholds. This is what we are addressing in this teaching… how the enemy uses our thoughts to build strongholds, and how strongholds affect our feelings.
