There are two basic world-views in this life. We either justify men or we justify God. Take for instance this statement: "The Bible says the best of mankind is evil." If you love God you will immediately nod with approval of that statement. You will justify God. If you haven't been converted, you will more than likely be quick to justify man (and of course yourself). You will say that people may have some faults, but they are basically good. The thought that anyone is evil (outside of Hitler and a few others) is repulsive and even disgusting. That's because you have you own definition of "evil." God's definition is anything that falls short of moral perfection... lying, stealing, ingratitude, hatred, greed, envy, jealousy, lack of love, blasphemy, self-righteousness, unbelief, disobedience, pride, and a multitude of other sins. If you think that you are up to God's standard (which He will use of Judgment Day) take this quick test with a tender conscience: www.needGod.com and if you are honest with yourself, you will end up saying, with the psalmist:
"Against you and you only, have I sinned, and done this evil in your sight: that you might be justified when you speak, and be clear when you judge" (Psalms 51:4).
