Here we see God coming in power and the earth passing away before him. God is a God of mysteries and apparent contradictions. Psalm 130 and Luke 12 speak of fearing God in the same line and breath as they say, because he loves you.
"If you, O Yah, should keep track of iniquities,
O Lord, who could stand?
But with you is forgiveness,
so that you may be feared.”
"But I will show you whom you should fear: fear the one who has authority, after the killing, to throw you into hell! Yes, I tell you, fear this one! Are not five sparrows sold for two pennies? And not one of them is forgotten in the sight of God. But even the hairs of your head are all numbered! Do not be afraid; you are worth more than many sparrows."
The fear of the Lord puts him in his proper place: as the unquestionable King of Everything with power to destroy all in his little finger who uses that power for your good because of his unquenchable love for you!
So while what is imperfect melts away like wax before his heat, what is perfect, faith, hope and love, pass the test and stand like glittering gold and diamonds before him. And the greatest of these, the most excellent way, is Love.
"I am the Way, the Truth and the Life, no man comes to the Father except through me." John 14
