Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness…let us watch and be sober.
1 THESSALONIANS 5:5, 6
We of the Christian faith need not go on the defensive, for it is the modern man of the world who is the dreamer, not the Christian believer!
The sinner can never be quite himself. All his life he must pretend. He must act as if he were never going to die, and yet he knows too well that he is. He must act as if he had not sinned, when in his deep heart he knows very well that he has. He must act unconcerned about God and judgment and the future life, and all the time his heart is deeply disturbed about his precarious condition. He must keep up a front of nonchalance while shrinking from facts and wincing under the lash of conscience. All his adult life he must dodge and hide and conceal. When he finally drops the act he either loses his mind or tries suicide.
If realism is the recognition of things as they actually are, the Christian is of all persons the most realistic. He of all intelligent thinkers is the one most concerned with reality. He pares things down to their stark essentials and squeezes out of his mind everything that inflates his thinking. He demands to know the whole truth about God, sin, life, death, moral accountability and the world to come. He wants to know the worst about himself in order that he may do something about it. He takes into account the undeniable fact that he has sinned. He recognizes the shortness of time and the certainty of death. These he does not try to avoid or alter to his own liking. They are facts and he faces them full on.
The believer is a realist—his expectations are valid and his faith well grounded!
