I think Dr. John Gerstner's article explains it very well.

I think that there is too much confusion today about God's love to use "God loves the sinner but hates the sin." What exactly are we trying to say by that statement anyway? Isn't it usually used to excuse away some sort of sin and say it isn't any big deal? Also, it's pitting love against hate, as though they are always direct opposites.

True godliness is a sincere feeling which loves God as Father as much as it fears and reverences Him as Lord, embraces His righteousness, and dreads offending Him worse than death~ Calvin
