I can pick on the above gentlemen as I too have been abundantly blessed with ears. The artists have over emphasized the ears of Barak Obama and Ross Perot. While they have big ears, these pictures are obviously an exaggeration of their size. The artists have focused on a particular attribute of their persons.
Many times this is what men do with God. They over emphasize a particular attribute of His nature until the picture they have of God is not true, but a caricaturization of Him. What we must do is put each of God's attributes in proportion to all his attributes, and not to the minimization or elimination of some.
Some people focus so heavily on the holiness of God that barely no one can be saved; after all their best efforts they even worry about themselves. Others focus so heavily on the mercy of God that no one will be lost, including: Dahmer, Hitler, Stalin and Hussein (not Barak). When you do this you have a distorted view of God. The mercy and holiness of God are not competing ideas that you have to accept one or the other. Both are true and are complimentary of each other.
"Mercy and truth are met together; righteousness and peace have kissed each other." Psalms 85:10 KJV
Let's view God how He is, and not how the human mind would portray Him by exaggerating the aspects of God's nature that we choose to emphasize.
