The whole head is sick, and the whole heart faints. from the sole of the foot even to the head, there is no soundness in it.
God our Saviour … desires all men to be saved and to come to the knowledge of the truth.
Isaiah 1:5.6; 1 Timothy 2:3.4
The prophet Isaiah starts his book with a moral diagnosis of mankind: he is sick from head to foot.
The sick feet are illustrative of his life’s walk, in which he fails to keep God’s standards. His head stands for his thoughts and understanding, which can so easily serve evil ends. His weak heart completes the picture of misery. Man lacks truly beneficial motives. His heart is not directed towards God. He has proved to be self-willed and hostile towards God.
The disease that has troubled man from his birth is sin. It exerts its disastrous, fatal influence incessantly. Can no-one come to our rescue then? Nobody apart from God. He alone can, and He is willing to do so. In His Word, the Bible, He sets out four steps to obtain healing: We must admit that we are “sick”, i.e. that we are sinners. The we must go to the right doctor. We must uncover the guilt of our life before God.
We are forced to accept God’s diagnosis: that we are lost for eternity. Finally, we must apply the cure He prescribes for us: faith in His Son, Jesus Christ, and His work of redemption. The atoning death of Christ is the necessary, infallible means of our thorough healing.
