He Reminisces On The Complacency That Had Been His When He Was Well And The Shock That His Illness Had Been To Him (Psalms 30:6-7).
As for me, I said in my prosperity,
I will never be moved.
You, YHWH, of your favour,
Had made my mountain to stand strong.
You hid your face,
I was troubled.
In a few short words the Psalmist brings out his own, and man's complacency. When all is going well men think that nothing can affect them, especially if they are prospering wealthwise. And yet he acknowledges that he had overlooked the fact that it was God Who in His favour and compassion had made his mountain stand strong. This may reflect the strength of Jerusalem, which was David's city, and that he was secure because God had made him so. Or it may simply indicate that the mountain of his personal life had been made strong. But either way he had grown complacent, had forgotten what he owed to God, and had begun to see himself as invulnerable.
But then God had hidden His face from him, and all his troubles had begun. What a shock it had been to his system. Suddenly he had realised that he was mortal. What an important lesson that is for us all to learn.
