Those who love to argue are self-absorbed, their entertainment is to frustrate others in debate and win over them through intimidation and mocking.
If discussion or debate is not based on learning a solution or increasing knowledge, then it has no value for emotional and Spiritual growth.
Discussion ought to be enjoyable for both parties to engage in intelligent conversation based on truth.
I have heard debates that make both parties look absolutely foolish. They will say the silliest things that are irrational to frustrate the other person, nothing is about truth but it is about agitating the other person, it has no purpose except to cause frustration.
I avoid these kinds of people. When someone walks into a room with an angry demeanor, a saunter in their walk, and a lack of graciousness on their lips, I leave the room.
There is reason to feel sorry for such people, they have no confidence or they would have no need to demean and mock others to elevate themselves, they are sorry specimens.
We know someone is not born-again when they live a lifestyle of anger and superiority. God removes these sinful traits from those He changes into a new creation.
When we have become born again the Holy Spirit comes to live in us bringing with Him the fruit of His Spirit.
Galatians 5:22-23
"22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; against such things there is no law."
We do not have to try to have these traits they are a part of us, and they are our automatic response to every situation. If we slip up and act badly we are convicted by the Holy Spirit and apologize quickly to resolve the hurt we caused. Those who live a lifestyle of anger and argument thinking it is legitimate to act this way, have never been born again. They remain in their sin without conscience over it. Sadly this mentality in our culture is growing and being treated as acceptable by many. God told us to get away from them, these people will never listen to the gospel having no desire to be changed by Christ.
2 Timothy 3:1-5
Difficult Times Will Come
"3 But realize this, that in the last days difficult times will come.
2 For people will be lovers of self, lovers of money, boastful, arrogant, slanderers, disobedient to parents, ungrateful, unholy,
3 unloving, irreconcilable, malicious gossips, without self-control, brutal, haters of good,
4 treacherous, reckless, conceited, lovers of pleasure rather than lovers of God,
5 holding to a form of godliness although they have denied its power; avoid such people as these."
Many of these debaters who are in love with themselves will claim to be Christian, as God said in verse 5, they "have a form of godliness" but are not saved. We are told to avoid these people.
If we are praying for them and they come around at some later time desiring to know Christ, then we can speak to them about Him, otherwise, we must obey God and avoid them.
