War actually involves physical violence
Nope, that is nothing more than your worldly carnal minded opinion.
This is the Religion board, here is some "religion" you might want to consider:
Luke 14:26-33 ASV
26 If any man cometh unto me, and hateth not his own father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple.
27 Whosoever doth not bear his own cross, and come after me, cannot be my disciple.
28 For which of you, desiring to build a tower, doth not first sit down and count the cost, whether he have wherewith to complete it?
29 Lest haply, when he hath laid a foundation, and is not able to finish, all that behold begin to mock him,
30 saying, This man began to build, and was not able to finish.
31 Or what king, as he goeth to encounter another king in war, will not sit down first and take counsel whether he is able with ten thousand to meet him that cometh against him with twenty thousand?
32 Or else, while the other is yet a great way off, he sendeth an ambassage, and asketh conditions of peace.
33 So therefore whosoever he be of you that renounceth not all that he hath, he cannot be my disciple.
Is he talking about physical war in the above passage?
Matthew 10:32-39 ASV
32 Every one therefore who shall confess me before men, him will I also confess before my Father who is in heaven.
33 But whosoever shall deny me before men, him will I also deny before my Father who is in heaven.
34 Think not that I came to send peace on the earth: I came not to send peace, but a sword.
35 For I came to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law:
36 and a man's foes shall be they of his own household.
37 He that loveth father or mother more than me is not worthy of me; and he that loveth son or daughter more than me is not worthy of me.
38 And he that doth not take his cross and follow after me, is not worthy of me.
39 He that findeth his life shall lose it; and he that loseth his life for my sake shall find it.
Is he talking about a physical sword of warfare in the above passage?
Surely he speaks of a sword of spiritual warfare.
Ephesians 6:10-17 ASV
10 Finally, be strong in the Lord, and in the strength of his might.
11 Put on the whole armor of God, that ye may be able to stand against the wiles of the devil.
12 For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world-rulers of this darkness, against the spiritual hosts of wickedness in the heavenly places.
13 Wherefore take up the whole armor of God, that ye may be able to withstand in the evil day, and, having done all, to stand.
14 Stand therefore, having girded your loins with truth, and having put on the breastplate of righteousness,
15 and having shod your feet with the preparation of the gospel of peace;
16 withal taking up the shield of faith, wherewith ye shall be able to quench all the fiery darts of the evil one.
17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
I fear for you, lest perhaps while feasting in the Word, certain ones of old time may have crept in unawares; certain ones having been named, certain ones having been written beforehand as fitted for destruction. Cut them off before they choke the Seed of the Word from the soil of your heart, (Parable of the Sower, and of course, Jude 1:4-15), for we wrestle not against flesh and blood and there appears to be a war raging in your heavens.
