“He put on righteousness like a breastplate, and a helmet of salvation on His head.” (Isaiah 59:17)
Paul wrote the Ephesians about putting on “spiritual armor” for the struggle against the powers of darkness. He likely drew this imagery from the praetorian guard who guarded him, but interestingly he may also have drawn from Isaiah 59:17 where we see similar imagery. The difference in Isaiah, though, is that God is the One who is clothed with the breastplate of righteousness and the helmet of salvation, while in Paul’s statement we are the ones who are to wear this armor.
At least part of what this suggests is that we are to put on GOD’s righteousness and GOD’s salvation as our armor. And to follow suit, we are to put on the belt of GOD’s truth, the boots of GOD’s good news, faith in GOD as our shield, and the sword of GOD’s word. In short, God is the One who provides this spiritual armor we need. Therefore, we are to rely solely on Him for the weapons for fighting the darkness of our world.
It’s all about Him.
Lord, You are the Source of our strength and the weapons of our warfare. We trust in You. Amen.
