A leading disinfectant spray claims that it “kills 99.9% of germs.” That sounds pretty impressive. You can’t get much closer to 100% than that. Due to scientific limitations and the existence of resistant microbes, it cannot guarantee 100% elimination of all germs. But 99.9% is good enough.
What if Bible promises worked that way? What if the blood of Jesus cleansed us from 99.9% of our sins? That would be pretty good. What if God heard 99.9% of our prayers? That’s a lot. What if the devil fled from us 99.9% of the times that we resisted him? Maybe that would be good enough.
But Bible promises don’t have scientific limitations and are not affected by resistant microbes. When God makes promises to us in the Bible, we can count on them as 100% true and 100% effective. The blood of Jesus cleanses from 100% of our confessed sins (1 John 1:9). Our Father in heaven hears 100% of our prayers (1 John 5:14). When we resist the devil, he flees 100% of the time (Jas. 4:7). Our God is not 99.9% God!
