In both the Old and New Testaments, we are commanded to "fear the Lord".
Fear the Lord your God and serve him. Hold fast to him and take your oaths in his name. Deuteronomy 10:20 ESV
Honor everyone. Love the brotherhood. Fear God. Honor the emperor. 1 Peter 2:17 ESV
However, in the first epistle of John, we are told that there is no fear in love, and that love drives out fear.
There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love. 1 John 4:18 ESV
So, in what sense are we to fear God, and in what sense are we not to fear God?
