Yea tho I walk through the valley of the shadow of death...David was in a valley, in a trial, most likely facing conflict and controversey. He was in the shadows. A shadow is created when something blocks the sun. In other words, the difficulty David was facing was obsecuring him from seeing the radiance and power of the Son! Many today may be walking in the shadows.....from your point of view you cannot see the power of God's glory. Your circumstances are hindering you from seeing your purpose, your destiny, and your divine assignment. But this I must inject a shadow cannot exist without the sun....what am I saying, your shadow, your trial you are going through cannot exist without the Son! Rejoice child of God, even tho you can't see it the Son is shining! You got to be like David! You can't be passive, don't sit down when in a season of shadows, but you got to Walk On! David said, "Yea tho I walk," In other words, get up out of your pity, despair, and problem and walk on! Why because the Son is shining! David understood this, that's why he said he would fear no evil....he understood the shadow was nothing more than a form that has no substance...no power...no authority! To sum it up .....Walk On today! Depart from your problem and start walking with the answer! (The Word of God) No weapon formed against you shall prosper! The Son is shining!
