Deuteronomy 1:30
The Lord (YHWH) your God who goes before you will Himself fight on your behalf, just as He did for you in Egypt before your eyes,

Our God is a mighty God! Some time later King Jehoshaphat of Judah trusted in that wonderful truth and spoke to his people when they were faced with the combined armies of their enemies. He said to his people saying that the Lord had told him not to fear that great multitude for the battle is not yours but God's! {2Ch.20:15}
 
We need to know today that when the enemy, that old serpent and his minions, come against us the battle is not ours but the Lord's—and He has already won. We have been given the victory through our Lord Jesus Christ! {1Cor.15:57}
 
Of course, we also need to know that we, the children of God, still have a part to play. In those battles of long ago the tribe of Judah which is the tribe of praise (yehûdâh — “praised”) was the tribe always leading the army into the fray. In every trial, every conflict that you and I encounter in life, we should always lead with praise. The apostle Paul taught that we should rejoice always, pray without ceasing, and in everything give thanks, for this is God's will for you in Christ Jesus'. {1Thes.5:16-18}
 
I have every confidence that being devoted to God's Word as the apostle Paul was he certainly would have been familiar with the 'battle plan' that had been provided through the prophet Isaiah when he wrote: “Sing to the Lord (YHWH) a new song, sing His praise from the end of the earth! You who go down to the sea, and all that is in it. You islands and those who dwell on them. Let the wilderness and its cities lift up their voices, the settlements where Kedar inhabits. Let the inhabitants of Sela sing aloud, let them shout for joy from the tops of the mountains. “Let them give glory to the LORD, and declare His praise in the coastlands. The LORD will go forth like a warrior, He will arouse His zeal like a man of war. He will utter a shout, yes, He will raise a war cry. He will prevail against His enemies.” {Is.42:10-13}

Paul and Silas certainly put that to the test when they were thrown into prison in Philippi and were then miraculously set free as they sang and prayed and praised the Lord in that dark place. The Lord shook the earth! {Acts 16:16-40}
 
Knowing that our warfare is not against flesh and blood but rather against the powers and the spiritual forces of wickedness, {Eph.6:12} we should also know that the battle was won when Jesus surrendered all to the Father saying to Him as He faced the cross, “Father, if You are willing, remove this cup from Me; yet not My will, but Yours be done.” {Lk.22.42} He then did give all on the cross of Calvary and said, “It is finished.” {Jn.19:30}

Like Jesus said, if we follow Him and are not willing to give our own lives and do not carry our own cross we cannot be His disciples! {Lk.14:26-27} And that should lead us and empower us to faithfully follow the command of Jesus in the Sermon on the Mount—our battle plan:
 
“You have heard that it was said, 'you shall love your neighbor, and hate your enemy.' But I say to you, love your enemies, and pray for those who persecute you in order that you may be sons of your Father who is in heaven; for He causes His sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.” (Matthew 5:43-45)
 
GOD KNOWS THE PLAN HE HAS FOR US
