“O LORD, rebuke me not in Thine anger, neither chasten me in Thy hot displeasure.”
To answer the title question; David the Psalmist thought God could be angry. To ask, “Is God angry?” makes it sound as though one is thinking that He is angry all the time, through all eternity.
The Psalmist is asking for mercy. Do I need mercy? Definitely. Do you need mercy? Yes. The human race needs mercy. Jesus said,
“Blessed are the merciful: for they shall obtain mercy.” (Matthew 5:7).
There seems to be a mistaken belief that God could never be angry. “How could a loving God be angry?” is the assumptive question. How could a loving God never be angry? would be my question and thought. If you love and someone hurts what you love does that not make you angry?
God loves His children. He has proven that by the cross of Christ. He poured out His anger upon His only begotten, sinless, spotless Son as He bled and died on the cross. Now He declares all who come to Him through Jesus Christ “Righteous”.
The writer of Hebrews has written,
“It is a fearful thing to fall into the hands of the living God” (Hebrews 10:31).
I am blessed to be in the hands of the living God. I do not want God to be angry with me. Like David I ask for His mercy. It is found in Christ.
