God is selfish. He wants everyone to believe in Him even though there's no rational reason to do so. Therefore, if you accept the basic tenets of Christianity (which inevitably lead to this conclusion) you also have to accept that He is not perfect, by His own definition. Therefore, His very nature as described in the Bible is contradicted by the reality you accept as a Christian. That one contradiction is enough reason to question everything in the Bible.
Actually, God is jealous, not selfish.
He states in both Exodus and Deuteronomy (10 Commandments) that he is jealous, and we should not bow down to images or idols (respectively) and/or Gods. But, if we look at God as jealous... who can he be jealous of? I believe, this, in itself, is proof of God's fallibility and his lack of absolute sole power. But, this in no way makes me question everything in the Bible.
Frosty the Snowman is happy, not compassionate.
It is stated in the song of our ancestors, Frosty the Snowman:
Verily, Frosty the Snowman
Was a joyous, nay, happy soul.
With yonder corncob pipe and button nose
And two eyes, of coal manufacture.
It is very clear here, that Frosty the Snowman has a "happy soul." Experts still disagree on what "button nose" means (viz., if it is a real button, or simply describes the shape of his nose). Also, evil secularists argue that eyes made of coal could not actually see. But we believe that coal simply means that his eyes were very dark, and did not have whites. They were manufactured by our Creator to look like coals. That's all.
