Nehemiah 4:20 In what place therefore ye hear the sound of the trumpet, resort ye thither unto us: our God shall fight for us.
When the Jews were rebuilding the walls of Jerusalem the workers were scattered to different places around the city. Nehemiah told them that if the enemy should attack in one place the workers there should sound the trumpet and the other workers should come running to help fight. Then he gives this promise from the Lord to encourage them in their effort: “our God shall fight for us.” He is saying, “You can do this. Be courageous and fight, for it is not you, but God who is doing the fighting.” The Lord had serious enemies who were dead set on leaving Jerusalem vulnerable and unprotected.
Nehemiah had to be certain that he was in God’s will and doing God’s work, since it was a formidable task and he couldn’t do it without His help and blessing. He knew he could count on the Lord’s promise to fight for him. Because he had such a faith he knew he could encourage the workers.
Our Lord will fight for us in our spiritual battles when we are going about our Father’s business doing His good works. Our Lord did not say all life would now be easy when we “suffer the slings and arrows of outrageous fortune,” or when we “take up arms against a sea of troubles.” But He did say He would fight for us, that we would come to the aid and support of fellow Christians in their spiritual struggles, and that others would support us. In our Christian fellowships we live safely and well under a spiritual prayer covering.
Jesus came from the heavenly realm to fight for us, and win. He will come again and win the last great battle. And He comes daily to deliver us from evil when we sound the trumpet (say our prayers and pray the Lord’s Prayer). We believe the promise, and so we pray. Psalm 50:15: “Call upon me in the day of trouble: I will deliver thee.”
