You are all sons of the light  and sons of the day. We do not belong to the night or to the darkness.  So then, let us not be like others, who are asleep, but let us be alert  and self-controlled.  -I Thessalonians 5:5, 6 
I have it in my head that I  have to be in control all of the time.  Mainly, I feel that way  about my emotions.  I am always left feeling at a disadvantage  if I lose my temper, become upset, or worse, begin to weep.  Maybe  this latter one troubles me so much because long ago I somehow came  to believe that real men don’t cry, or it’s somehow not manly to  shed tears.  I devoted a lot of energy in my early adult life to  not allowing myself to weep under any circumstances.  My, am I  paying for that now. 
 I find that these days I will  become emotional over situations that years ago would not have affected  me that way.  I get teary-eyed when I hold my little grandson,  I will get weepy when I think about what fine young men my sons are  growing into, and when I begin to consider the amazing grace of God  – who has poured out His blessings on a sinner like me, then I truly  feel some powerful emotions.  I would love to be in control of  my emotions all of the time, but sometimes some tears can be healthy.   Whoever said that men should never cry honestly didn’t understand  the depths of human emotion. 
Of course, the Word of God  speaks of another kind of self-control that is centered on personal  conduct and thought processes.  We are admonished in scripture  to keep our minds alert to anything that might pull us off track and  derail our walk with Christ.  We are called to walk daily in the  light of the Lord Jesus.  His light is to radiate from us as a  witness of His grace in our lives.  As we walk in the light of  Christ we give light to a world that for too long has been shrouded  by the darkness of sin and evil.  Someone has said that rather  than curse the darkness we can light a candle.  If the light the  scripture speaks of is the love of Christ in us, then why not fan that  flame into a roaring blaze?  And while we’re at it, why not let  that blaze catch into all aspects of our lives?  The darkness that  is all around us is not only pierced, but overcome by that light.
