I once read the story of a man who crossed the Mississippi on foot when it was frozen over. Half-way across he lost confidence and began to panic. He finished his crossing crawling on his stomach, soaked and chilled. Imagine his face when almost immediately after standing on shore he saw another man, sitting on a large sled loaded with pig iron, wave cheerily as he passed and drove over in complete safety! Now it will be like that for some Christians … supported ‘only’ on the promises of God. Some will go through their whole pilgrimage worried, fretting, hardly daring to believe that their God and Saviour can cope with their failures and doubts and fears and will keep them to the end. Others press on with confidence … sometimes slipping but regaining their foothold and pressing on.
