a peace that passes understanding

If you run in the Christian circle, you undoubtedly know the phrase "a peace that passes all understanding". It's taken from Phil 4:7.

I have been thinking a lot about this phrase...and the responsibility that comes with it. As we walk through life's circumstances, we face trials. Those who don't know the Lord watch us closely. They want to know how we will handle situations. Will we crumble? Will be hold on to Jesus? Or will be grumble and complain like many? We have the choice to make and a testimony to uphold.

When I find myself in a trial, I worry. I allow my mind to race, play out different scenarios, and oftentimes become physically ill. I deny that peace the Lord gives us. It's almost a minute by minute battle that I have with myself and the Lord.

But as a Christian do I not have the responsibility to show the strength of the Lord? That even when I am facing something difficult, I can still find peace? But at the same time, I want to be real about the struggle.

I am finding myself in this place of figuring out the balance. How do I grasp onto His peace without hiding the mere fact that it's difficult. How do you explain that to nonbelievers and maintain His name?
