Contra, God the Father, Jesus, and Holy Spirit have emotions and interact with them in a healthy and functional way. But controlling emotions, rather than relating to them like God does and has designed human's emotional systems to operate, is not a good idea since you're only as sick as your secrets and buried feelings never die. When a person attempts to control their emotions rather than relate to them lovingly and respectfully, they end up with a pile of unfelt emotions and feelings, which leads to acting out in unhealthy, perhaps codependent behaviors.

I didn't say sin is "just private." I said whether or not I sin is none of YOUR business, but I guess you can try to put words in my mouth if you want to, that's on you.

What I should have said earlier instead of saying sin has nothing to do with one's development of emotional intelligence, which isn't true, is that whether or not a person sins doesn't negate my point that dangerous men are in touch with their emotions. I'm not trying to assert that a person should ignore sin and simply build emotional intelligence. Because you've insisted on asserting that controlling one's emotions is a better way of operating, which I disagree with, what I'm saying is that operating as one with God, including relating to one's heart and/or emotions, in order to be dangerous and in touch with one's emotions as God does, is a healthier and more functional way of living.

When a person comes to grok how God's designed a person's emotions to work, and relate to and steward them well as God has intended, then it helps to produce positive life outcomes. The same goes for how to operate in relationship with one's spirit, soul as a whole, and body, and more.

When a person operates in Christ as one with God, sin isn't the focus, God is. In this context, sin isn't even appealing or desirable because a person is operating out of the desire and value set of God, in some sense. Some Christians, which may include you, like to maintain a focus or a fear of sin, rather than Jesus, and so end up becoming sin centered rather than Jesus centered. Personally, I'd rather abide in relationship to Jesus and his and the Father and the Holy Spirit's love, taking his perspective on all things in some sense, rather than worshipping sin by focus on it or becoming obsessed with it, since what we worship is what we become. Yes, sin exists and a person should repent, confess it to God and a trustworthy community if they happen to commit sin, but Christians are not longer sinners, but saint with the righteousness of Jesus as their core nature. Because of being made the righteousness of Jesus, Christians are no longer inclined to sin though it remains a possibility because they have agency.

The self-control Galatians 5:22 speaks to could be more accurately interpreted or translated as self-direction, the ability to make choices and follow through on them.

"But Scripture calls us to rule our spirits (Proverbs 16:32)" In some sense, you're conflating one's spirit with one's emotions, but these are not technically the same. I would ask you not to conflate emotions and spirit, but to distinguish between them.

Jesus died and rose from the dead for a number of reason, which include salvation, but certainly do not end there. Jesus died and rose again to free us from sin, to provide a path to the Father, and to make us whole in spirit, soul, body, heart, mind, will, and emotions.

Isaiah 61:1

The Spirit of the Sovereign Lord is on me,

because the Lord has anointed me

to proclaim good news to the poor.

He has sent me to bind up the BROKENHEARTED,

to proclaim freedom for the captives

and release from darkness for the prisoners.

Men and women are called to steward and direct and lead their emotions, not control them, and one of the reasons we know this is because emotions can't be controlled, they can in some sense only be related to. So it behooves men and women to relate to them well, to notice, accept, validate, discuss them with Father, Jesus, and/or Holy Spirit, and have them healed if they are negative emotions or feelings. As I've said before, feelings are good indicators but bad dictators.

Healthy and functional people seek a balance between being dangerous (competent) and being in touch with the emotions and or feelings they are experiencing, under the leadership of their spirit, under the leadership of Father, Jesus, and Holy Spirit. This brings them under the will of God. Jesus is certainly conscious of the emotions of people, and wants them to experience joy and peace and to get healed of sadness and pain:

John 15:11 - "These things I have spoken to you, that my joy may be in you, and that your joy may be full."

Isaiah 26:3 - "You keep him in perfect peace whose mind is stayed on you, because he trusts in you."

Revelations 21:4 - "He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.”

Therefore, the idea that Jesus didn't die so that we could feel good is absurd and unscriptural. That is exactly one of the intents of Jesus death and resurrection, to restore our emotions to a Heavenly state.

Matthew 6:10 - "Your kingdom come, your will be done, on earth as it is in heaven."

And the Kingdom of Heaven is in the Holy Spirit.

Romans 14:17 - "For the kingdom of God is not a matter of eating and drinking but of righteousness and peace and joy in the Holy Spirit."

Notice that two of matters of the kingdom of God are emotional or feelings states, peace and joy, in the Holy Spirit.

John 14:26: "But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you."

Part of the explicit role of the Holy Spirit is to comfort people's emotions/feelings, who the Father sent after Jesus death and resurrection.

But controlling your emotions and/or feelings, especially on your own without disclosing them to God if that's your habit, is a bad idea.
