The Bible is absolutely emphatic about the fact that we will not find the truth by ourselves, within ourselves. We cannot diagnose ourselves. One telling statement is found in Jeremiah 17:9—“The heart is deceitful above all things, and desperately sick; who can understand it?”
The heart sees what it wants to see, and conveniently finds inconvenient truths invisible. Self-diagnosis is hopeless.
To understand Jesus, we must begin where His thinking begins: not with John 3:16, but with Genesis 1:1, and on through all that follows. There we find the truth that forms the basis of Jesus’ teaching, truth that we would never find within our own deceptive, incurably sick hearts. To understand who Jesus says that we are, we must understand who we were, and what we became, and how we got there.
