Well I will pass on all that - I have no calling to endtimes issues. I do know most are wrong about what they believe, otherwise there would be more agreement.
I suspect you have an answer for 2 Tim 2:4...
"No man that warreth entangleth himself with the affairs of this life; that he may please him who hath chosen him to be a soldier...."
Paul uses a soldiers life to illustrate a point about spiritual life. No mention here or anywhere about believers ceasing to be soldiers.
Rom 13:4 speaks of civil authorities bearing the sword to be feared, as they have God's ordinance to kill.
I suspect we won't get much further with this - even Rev 19:11 speaks of God waging war and smiting the nations (verse 15) this is not Old Covenant.
Lastly your focus on the 'Law of Christ' I find a bit sad as the anointing within is meant to be our teacher and instead you present another bunch of 'Laws' instead of encouraging folks to walk in the freedom He gives us in the Spirit. John 2:20-29
The Law could never lead folks to righteousness, it only serves the purpose of exposing sin.
The Law of the Spirit within us however, gives His heart on every circumstance we face as we walk in the Spirit, and as He within us partners in our life choices. (when we let him)
2 Tim 2:3-4
3 Thou therefore endure hardness, as a good soldier of Jesus Christ.
4 No man that warreth entangleth himself with the affairs of this life; that he may please him who hath chosen him to be a soldier.
Christ has called us to be his soldiers waging spiritual warfare against all wickedness, using not carnal but spiritual weapons(sword of the word/spirit), Paul wasn't speaking of soldiers of this world but the Spiritual soldiers of God.
Romans 13 is not speaking of civil rulers but spiritual, short study on that here:
"Let us Learn the True meaning of Romans 13:
99.9% of pastors today teach that this refers to governments and rulers of the world. But taken/understood by the spirit of YHWH truth shows us that it is reffering to God and true ministers of Christ Yahshua only Rom 13:1 states that there is no power but YHWH. Also YHWH/Yahshua ordains those to teach his word ordinance's/laws/commands/doctrine All Are subject to the commands of God not those of the world. Romans 13:2,
Whosoever resistith the law/commands of YHWH/Yahshua resistith God, and will be damned. Rom 13:3 who are these rulers? See Romans 12:8. Romans 13:3-4 for ruler of the church of God. Those who teach his doctrine/gospel/commands are not against good, but against evil. His ministers shall praise all that follow christ and his laws/doctrines/commands. They, God's ministers, shall bring the (word of God)the sword against all evil workers. Heb 4:12, matt 10:44.
Heb 13:6-7
6 So that we may boldly say, The Lord is my helper, and I will not fear what man shall do unto me.
7 Remember them which have the rule over you, who have spoken unto you the word of God: whose faith follow, considering the end of their conversation.
If Romans 13 refers to worldy rulers and governments. It would refer to all the governments in history. Such as Ceasar, Hitler, Mao, Sadam, etc. Did they reward Christ follwers for doing good?
1. Whom put Yahshua to death?
2. By who's Laws/authority?
3. Did he do Evil?
4. What Authorities put the Apostles to death?
5. Was it for doing evil? Romans 13:3-4
6. Did the worldly authorites praise Yahshua and the Apostles for doing good work? Matt 10:18-20 "18 And ye shall be brought before governors and kings for my sake, for a testimony against them and the Gentiles.
19 But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak.
20 For it is not ye that speak, but the Spirit of your Father which speaketh in you.
;Romans 13:3
Rulers of God's church (Romans 12:8) by rightly dividing the word of God we see that Romans 13 is not speaking to worldly governments. But is speaking of those whom God has called to lead the church in all truth and goodness. His ministers/rulers(Romans 13:6) teaching all his commands/doctrine/ordaninces. Rom 13:2,9-10 Laws of God. Yahshua and the Apostles teach us to follow God not man, but if man's law is NOT against God's we are to follow it.
Daniel 6:8-16
Daniel 3:12-29
Acts 5:27-29
27 And when they had brought them, they set them before the council: and the high priest asked them,
28 Saying, Did not we straitly command you that ye should not teach in this name? and, behold, ye have filled Jerusalem with your doctrine, and intend to bring this man's blood upon us.
29 Then Peter and the other apostles answered and said, We ought to obey God rather than men.
Peace "
Now again God wages war on the wicked, and during the end times all those who take the mark of the beast cannot be saved and will be destroyed by the Lord. Again his Character did not change he is still a jealous vengeful God.
We are not to use our freedom in Christ to sin(Romans 6:1-2).
The word of God tells us that sin is transgression of the Law(1 John 3:4) for where there is no law there is no Transgression(Romans 4:15) we do not make void the Law through faith(the law which is of faith-Romans 3:21-22,24-27) but establish it(Romans 3:31) this is how we know God to keep his commandments(1 John 2:3) those who say they know Christ but keep not his commandments are a Liar and the Truth is not in them(1 John 2:4) by this we know that we love the Children of God when we love God and keep his commandments(1 John 5:2) for this is the Love of God, that we keep his commandments and his commandments are not grievous(1 John 5:3) blessed are they that do his commandments that they may have right to the tree of life, and may enter in through the gates into the city(Revelation 22:14; Isaiah 66:23).
The Law of Christ shows us how to walk in righteousness as the Lord wants us to walk, doing those things that are pleasing in his sight. Without a Law there is no sin, and if there is no sin then there is no need for repentance or for Christ's Atoning blood.
