Life can be tough. Anyone who has lived any amount of time on this blue marble we consider home recognizes this fact. It doesn't matter where you live or where you grew up; at one point or another, life will be difficult. I remember my college biology teacher telling us that he could, without knowing us individually, divide us into two groups: those who had experienced trials and those who eventually would. I remember thinking 'Yikes! That's scary.' What I have since learned is that he was right. I do not remember if he went beyond that statement to give advice, but if I could sidle up to my college freshman self just after that statement was given and tell myself one thing, it would be this: during good times and tough times, as much as you can, preach at yourself.
I am not, of course, suggesting you go out and get yourself a pulpit to stand behind, but I will resolutely state that nothing aides in approaching life and plugging away through difficult times like preaching at yourself and repeating the various Bible truths you know about your Lord and Savior. Like the fact that nothing is too hard for Him - He who created the heavens and earth. He who holds the spinning world in His hands. He who caused the deaf to hear and the blind to see. He who took upon Himself the sin of the whole world! He who died to take the punishment every human being deserves. He who rose from the dead to triumph over sin and death itself. Nothing is too hard for Him! There is no sickness He cannot heal, no sin He cannot forgive. No life He cannot redeem, no situation He cannot work in! There is no mountain too high He cannot help us over it, no valley too low He cannot get us out of it. He is good and He is God and nothing is too hard for Him!
Yes, preach at yourself. Every day. During good times and hard. Because through it, worry will be turned into confidence, fear turned into rejoicing, and doubt will be turned into praise.
