Today show no mercy to the past enemies that once had a hold on you. Compromising allows the enemy to distract, delay or keep one from reaching goals.
Read: Deuteronomy 7:1-2
“When the Lord your God brings you into the land you are about to enter and occupy, he will clear away many nations ahead of you: the Hittites, Girgashites, Amorites, Canaanites, Perizzites, Hivites, and Jebusites. These seven nations are greater and more numerous than you. 2 When the Lord your God hands these nations over to you and you conquer them, you must completely destroy[a] them. Make no treaties with them and show them no mercy.
