Because a brain with a positive attitude has higher levels of dopamine and serotonin, it is more successful and productive. Daily meditation on God's Law and His Word will increase feelings of calm and empathy, rewiring our brains to be more positive. Anticipation of promised future rewards will also lead to feelings of joy. We should be performing conscious acts of goodness and reflecting upon these deeds, realizing that charitable deeds to those deemed insignificant are in reality done for Christ Himself. Satan has rewired our carnal nature to be negative; we need to daily reprogram our neural pathways using words of affirmation, meditation and prayer, constantly comparing the fruits of Satan's negative attitudes with God's positive outlook. If we follow our Savior's example of living as profitable servants, we have a promise of joy that cannot be taken from us.
