“By the word of the Lord were the heavens made, their starry host by the breath of his mouth.” “For he spoke and it came to be; he commanded, and it stood firm.”
No doubt in my mind. Nothing happened by chance!

“For you, O God, tested us; you refined us like silver. You brought us into prison and laid burdens on our backs.
How does He refine us? He turns up the heat. How does He turn up the heat? He puts burdens on our backs. He puts trials in our lives. Why? To make us purer. Easier to take knowing this isn't it?

“If I had cherished sin in my heart, the Lord would not have listened.”
We can cry out to Him, but if we harbor sin, will he listen??? Good reason to confess our sins when we go to Him in prayer. So often in the psalms praising Him is directly related to the blessings.
