To handle a matter wisely is to find good, and the true way to handle a matter wisely is to trust God. This checkup, like every event under the sun, falls within the realm of temporal things wherein we are not to be idle or rash, but acting in all prudence, we are to rely simply and entirely upon Him. You do well to bring this request, for that in itself is an act of trust, acknowledging that the living God has a heart that hears and a hand that moves.
Consider who this God is to whom you look: He is the God of peace. He created peace originally, He restores it, He preserves it, and He shall ultimately perfect it. The peace which passes all understanding is first and fundamentally peace with God through the blood of the everlasting covenant. When a soul knows it is right with God through Jesus Christ, then it can reason, "If God is my God, the chief thing is secured and all the rest will be right." Is the God of Jacob the God of this generation in your household? If He is your God and your mother’s God, you have no cause for ultimate fear. The stones of the field are in league with the man who is at peace with God.
But remember, the peace of God is not a mere quieting of natural anxiety which forgets God. That is a false peace, a writing on the sand. True peace looks the matter full in the face and sees God in it. It says, “This God is our God forever and ever; He is a thinking God, an active, working, personal God who comes into the midst of this world and does not leave it to go on by itself.” Therefore, trust in the living God concerning your mother’s bodily frame, which His hands have made. He who paints every flower and hears the young ravens cry is not absent from the physician’s chamber. Trust in Him, and you will not have to mourn because you have used sinful means to grow rich in comfort, nor will you be tossed about by every wind of circumstance. O taste and see that the peace of God is good, for in very deed it surpasses all the tongues of men and of angels to set it forth. Whether the report brings ease or new trial, on Jesus' bosom nothing but calm is found.
