By the self-sufficiency of God we mean that God is unique, solitary and self-sufficient in all his excellency.
Exodus 5:11 says,
“Who is like you, O Lord, among the gods? Who is like you, majestic in holiness, awesome in glorious deeds, doing wonders?”
The answer is that there is no-one like God. The first four words in the Bible, “In the beginning God”. God was there in the beginning. God was there in eternity past and will be there in eternity future. Before there was anything, God was. During a past eternity, God was alone, self-contained, self-sufficient and self-satisfied; God was in need of no one or no thing. God did not need heaven, or angels, or a universe, or an earth, or human beings, or you. God was not lonely, or sad, or lacking anything. God was under no constraint, or obligation, or necessity to create anything; God was and will always be self-sufficient.
The Sistine Chapel ceiling was painted by Michelangelo between 1508 and 1512 at the commission of Pope Julius II. Michelangelo, who was not primarily a painter but a sculptor, was reluctant to take on the work. The Pope however was adamant and Michelangelo had no choice but to accept. The work is now considered a masterpiece. God is depicted as a strong man with a flowing beard, or as Joe Bell joked, Father Christmas on steroids. Of course this representation of God is just an artist’s impression, nevertheless, it is good to ask ourselves: do we have a correct view of God?
