In Psalm 27 David makes the amazing statement:
3 Though an army may encamp against me,
My heart shall not fear;
Though war may rise against me,
In this I will be confident.
In these words we find deep truths.
He tells us where in life the real battle lies. That it isn’t on the outside. It isn’t the outside stimuli, the army or the war we face, that determine what happens to us or how things affect us, but its the internal choice, response we make to the stimuli. The internal choice in our heart whether to fear or not, be confident or not. What goes on inside us, that’s the deciding factor.
In this he reminds us we have a choice, we are not helpless victims of what goes on around us or what happens to us in life.
The real battle lies in the heart. If we can keep our heart sound, healthy, free of fear it doesn’t matter how big the army is we face or how fierce the war is against us, we are not a victim. We have a choice, we’re nor defeated.
Later in the Psalm David adds another truth related to this:
13 I would have lost heart, unless I had believed
He tells us just what we must do to win the battle in our heart. We must believe. Its in believing that we win the internal battle, the battle of our heart. If we maintain the belief that whatever we face, however big it is, God is with us, He loves us and has not abandoned or forsaken us, but will help us, then we remain victorious.
Our believing and trusting in God, maintaining faith in Him, keeps us connected to Him and therefore connected to what makes the difference. Through faith we bring God and His limitless resources into the situation.
So David tells us in these two verses where the real battle lies and what the real battle is.
It lies within us in our heart, and the battle is to believe.
