The way to control our emotions is to control our minds, renewing them by the daily input of scriptural principles, the knowledge of God, and meditation on His attributes. Then the Holy Spirit, along with the Word of God, will bring about appropriate emotions based on truth. When we immerse ourselves in the only means of our sanctification—the Bible—we arm ourselves with the only effective weapon against out-of-control emotions. Then we can control our emotions instead of them controlling us. In themselves, emotions are not unbiblical, but they are indications of what is in our hearts
Galatians 5:19-26 (NLT) When you follow the desires of your sinful nature, the results are very clear: sexual immorality, impurity, lustful pleasures, idolatry, sorcery, hostility, quarreling, jealousy, outbursts of anger, selfish ambition, dissension, division, envy, drunkenness, wild parties, and other sins like these. Let me tell you again, as I have before, that anyone living that sort of life will not inherit the Kingdom of God.
But the Holy Spirit produces this kind of fruit in our lives: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. There is no law against these things!
Those who belong to Christ Jesus have nailed the passions and desires of their sinful nature to his cross and crucified them there. Since we are living by the Spirit, let us follow the Spirit’s leading in every part of our lives. Let us not become conceited, or provoke one another, or be jealous of one another.
