In the 17th century, a humanist scholar by the name of Muretus was an ailing fugitive in France. When he presented himself to the medical doctors, he was dressed in rags. The doctors discussed his case in Latin, thinking he would not be able to understand. A doctor said, "Faciamus experimentum in anima vili" (Let us try an experiment with this worthless creature). To their shock this pauper replied, also in Latin, "Vilem animam appellas pro qua Christus non dedignatus est mori?" (Will you call worthless one for whom Christ did not disdain to die?)
Saint Paul, in his letter to the Corinthians, writes, "But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us" (2 Corinthians 4:7). He describes those earthen vessels as dying men, troubled on every side, cast down yet not forsaken or in despair, those men used by God are constantly groaning under the burden of their bodies, waiting anxiously to be clothed with new ones.
God laughs at our egotistical efforts at being good because He never uses the high and mighty. But, instead the weak of this world to confound the wise. Saint Paul writes, "For you see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called but God chooses the weak and despised of the world to confound the mighty so that nobody should glory in His presence" (1 Corinthians 1:26-31).
God calls us in our weakness though He knows we may fail at times. Yet He puts His priceless treasure in these earthen vessels that we are and does the impossible with nothing. He looked down on a scheming, base, weakling named Jacob and said, "Fear not, thou 'worm' Jacob. I will help you. Behold, I will make you a new sharp threshing instrument having teeth and you shall rejoice in the Lord" (Isaiah 41:14-16).
People often seek God to achieve fortune, fame, honor and respect. But God is not impressed. So let not your heart be troubled when you feel weak. For in your weakness, God uses you and makes you strong.
