Many theologians attribute omnibenevolence to God almighty. For example Louis Berkhof an American-Dutch reformed theologian regards God as omnibenevolent.
As for it being mentioned in the scriptures, Romans 11:12 "God is the final standard of good, and all that God is and does is worthy of approval", being the final standard of good implies that God is incorruptibly good....or omnibenevolent.
Also to suggest that God isn't omnibenevolent is to suggest that God has a portion of evil within him. If he is not all good, then he is either a mixture of good and evil or completely evil. I have been brought up to believe that God is all good and like to think it so.
Omniscience is a term meaning all knowing, yes the terms you have provided are also affiliated with God, however so is Omniscience. Which brings me back to my original question.
Allow me to elaborate on my original query. In order to be all knowing God must know every feeling that has ever been felt by anyone for every reason. As there have been an uncountable number of cases where an innocent child has been killed God would hence know what it is like to kill one.
My question is how can one be all good and yet know what it is like to commit such malevolent actions.
Of Sin
Of sin, because they believe not on me; John 16:9 (King James Version)
And Of God
Every good gift and every perfect gift is from above, coming down from the Father of lights with whom there is no variation or shadow due to change. James 1:17 (English Standard Version)
So Beloved, What's The Beef?
Yes, they knew God, but they wouldn’t worship him as God or even give him thanks. And they began to think up foolish ideas of what God was like. As a result, their minds became dark and confused. Claiming to be wise, they instead became utter fools. Romans 1:21-22 (New Living Translation)
And, What To Do?
For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. John 3:16 (New International Version)
Love, Joe
