I want to end this series of posts with an analogy.
Eight years ago I was experiencing some unusual symptoms of something being wrong with my health. I was losing weight rapidly (something that never happens! I can eat 1000 calories a day and not lose weight). I went to an MD and they ran a series of tests. I wanted to diagnose myself. The doctor would not hear of it. He was skilled, I was not. he directed the testing process. Each of the tests looked into my body in a way my eyes could not. They were medically introspective. A surgical biopsy was necessary to see the depths of what was going on. And the tests/surgery brought a clear diagnosis -- I had multi-focal papillary carcinoma in my thyroid gland. Or, in simpler terms, I had thyroid cancer. It is the most treatable form of cancer but it did require treatment.
Now, at the point at which the introspection of my body brought a clear diagnosis, did I ask for more tests, more scans, more surgery? No I did not. They did the surgery, removed the gland, treated me with a radioactive substance a few weeks later, and have done regular scans of my whole body at regular intervals since. I am free of the cancer!
Introspection led to treatment . . . and so it is with the Christian. Yes, we must introspect to know our hearts, but that journey must be done with the direction of our Great Physician. I am not able, by myself, to see my heart accurately. I am not able to, even though I am armed with the doctrine of total depravity! I must be in a position of faith toward my God to ask him to show me my heart, knowing that this foul cesspool of mixed motives is also magnetic to me -- and I must have help from my savior, or I will be drawn into endless self-contemplation.
I know it is God who leads me to know myself because God the Spirit will always lead me to know my heart in the presence of the cross -- in the light of sin fully atoned for. He will point out my sin and quickly flood his light onto the Savior. His goal in conviction is not self-absorption but worship of the Savior who died for me and whose blood will change me.
i think Wesley had it right:
Thou, O Christ, art all I want, more than all in Thee I find;
Raise the fallen, cheer the faint, heal the sick, and lead the blind.
Just and holy is Thy Name, I am all unrighteousness;
False and full of sin I am; Thou art full of truth and grace.
Plenteous grace with Thee is found, grace to cover all my sin;
Let the healing streams abound; make and keep me pure within.
Thou of life the fountain art, freely let me take of Thee;
Spring Thou up within my heart; rise to all eternity.
