What does it mean to make flesh your arm?

In Jeremiah 17:5, to 'make flesh your arm' means to depend on human capabilities and wisdom instead of trusting in God's supernatural strength. This reliance on flesh leads to spiritual vulnerability and is denounced as a curse. Scripture teaches that our flesh is weak and cannot provide the sustenance or help we need for spiritual life. Thus, believers are called to redirect their trust from fleshly means to the unfailing power of God, who equips and strengthens us for every good work.
