Psa 3:3 But you, O LORD, are a shield about me, my glory, and the lifter of my head.
As David faced tremendous threats in his life, he armed himself with 3 certainties. #1. The Lord was his shield: over the lion, the bear, Goliath, Saul, and from all his adversaries. He trusted God to continue by His power and truth to be his shield and buckler from the fiery darts of the enemies. #2. The Lord was his glory: He raised a shepherd boy against all resistances to be a king. He who began a good work in him was faithful to complete it despite every challenge. #3. The Lord was the lifter of his head: He was his consolation in times of hanging his head down in defeat and fear.
“Hanging in there” is anything but a scriptural, the term “stand still” is. Those “hanging in there” are scarcely making it and get drained quickly (take a stab at hanging suspended from the ground, and see how long you can hang). God’s word for us, “ …position yourselves, stand still and see the salvation of the LORD, who is with you”(2Chr 20:17). God gives His people comfort, peace, and joy to lift them up; He is the shield for the weary.
A believer should confess, “I am standing in there” on the promises of God (He is our shield).
“Therefore, my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your labor (toiling) is not in vain in the Lord” (1Cor 15:58).
Having done all you can by the grace of God “stand“.
