My shield

(James Smith, "Wealth for Souls" 1859)

The privileges of the godly are many and great—but this is an especial one: "My shield is God Most High, who saves the upright in heart." Psalm 7:10

This implies exposure to foes—Satan, evil men, and death—against these we need defense. 

It implies opposition—and the opposition of our foes is great, daring, and deadly. 

It implies danger to be apprehended—because we are weak, timid, and unskillful—and our foes are strong, daring, and experienced. 

Our safety therefore, stands in what the Lord is to us—He is our shield, and such a shield as no one besides has, or can have. 
He is omniscient to see all our foes and dangers. 
He is omnipresent to help us at all times, and against all opposers. 
He is omnipotent to defend us, and secure us from all evil. 
He is faithful to fulfill His word, and carry out His engagements. 
He will come between the believer and danger. 
He will preserve the trusting soul from all real injury. 
He will protect the upright in heart everywhere, and at all times. 

What a mercy! What an unspeakable privilege is this! 

"You who fear the Lord—trust in the Lord! He is their help and shield." Psalm 115:11. O for grace to trust the Lord with all, to trust the Lord for all, and to trust the Lord under all! Holy Spirit, strip us of all confidence in the flesh, of all reliance on man, and of all trust in circumstances; and bring us by Your divine and holy teaching—to trust in the Lord alone!

"He is my loving God and my fortress, my stronghold and my deliverer, my shield, in whom I take refuge." Psalm 144:2
