God fights for us
Our battles belong to the Lord, at least for those who put their trust in him. For many they find themselves fighting alone with whatever armament they might have. But for the believer and follower of Christ, many of our battles are fought by the Lord. King Hezekiah was a king none like any other, because from the very get go of his reign he set his heart to please the Lord. The Assyrian king and his mighty army came to take Jerusalem, but because God was with Hezekiah, and he defied the Lord he could not (2K19:32-34). Throughout the scriptures we find God fighting for his people. Another example we find in the scriptures is when the children of Israel came out of Egypt and were trapped between the Red Sea and the army of Pharaoh that God fought for them (Ex14:13-14). We find in the Old Testament many verses that tell us that God fights for his people, but in the New not so many. In fact, the scriptures tell us that God will pay retribution to those who trouble us (2Th1:6). That we have to fight the good fight of faith (1tim6:12).
Deuteronomy 20:1
When you go to war against your enemies and see horses and chariots and an army greater than yours, do not be afraid of them, because the Lord your God, who brought you up out of Egypt, will be with you.
Paul tells us that we have to put on the armor of God (Ef6:10-12), so that we can stand in the time of evil. So, now in the New Testament the battle is for the believer, but it is not to say that God is not with us for Paul tells us that if God is with us who can be against us. God set some rules for when his people would go into battle like for any and the first thing was that they could not be afraid. Fear of war is the first thing that needs to be eliminated from the warrior before engaging (Det20:3). The next rule was that those who were going to war should not have anything pending in their lives such as new properties, business, or relationships lest if he died, he would leave it to someone else (Det20:5-7). We see this when Jesus tells the parable of the invitation to the great banquet (Lk14:18-19), that one after the other made excuses for not coming. They had things pending that affected their call to participate in the event. The kingdom of God has had an escalating war against it since Christ came, and in order for anyone to have a complete enough experience they need to take it by force (Mt11:12).
32 “Therefore this is what the Lord says concerning the king of Assyria: “‘He will not enter this city or shoot an arrow here. He will not come before it with shield or build a siege ramp against it.33 By the way that he came he will return; he will not enter this city, declares the Lord.34 I will defend this city and save it, for my sake and for the sake of David my servant.’”
Exodus 14:13-14
13 Moses answered the people, “Do not be afraid. Stand firm and you will see the deliverance the Lord will bring you today. The Egyptians you see today you will never see again. 14 The Lord will fight for you; you need only to be still.”
6 God is just: He will pay back trouble to those who trouble you
1 Timothy 6:12
12 Fight the good fight of the faith. Take hold of the eternal life to which you were called when you made your good confession in the presence of many witnesses.
Ephesians 6:10-12
10 Finally, be strong in the Lord and in his mighty power. 11 Put on the full armor of God, so that you can take your stand against the devil’s schemes. 12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.
Deuteronomy 20:3
3 He shall say: “Hear, Israel: Today you are going into battle against your enemies. Do not be fainthearted or afraid; do not panic or be terrified by them.
Deuteronomy 20:5-7
5 The officers shall say to the army: “Has anyone built a new house and not yet begun to live in it? Let him go home, or he may die in battle and someone else may begin to live in it. 6 Has anyone planted a vineyard and not begun to enjoy it? Let him go home, or he may die in battle and someone else enjoy it. 7 Has anyone become pledged to a woman and not married her? Let him go home, or he may die in battle and someone else marry her.”
Luke 14:18-19
18 “But they all alike began to make excuses. The first said, ‘I have just bought a field, and I must go and see it. Please excuse me.’19 “Another said, ‘I have just bought five yoke of oxen, and I’m on my way to try them out. Please excuse me.’
Matthew 11:12
12 From the days of John the Baptist until now, the kingdom of heaven has been subjected to violence,a] and violent people have been raiding it.
