This past week, my Bible reading plan had me in the book of Mark. Specifically as I read Mark 13 & 14, there were two phrases that seemed to be on repeat. Repetition usually means this is important; pay attention.
- Be on guard
- Keep watch (be on alert)
I encourage you to read both chapters, and notice how these words continue to show up.

All things considered, they’re a helpful pair to hold on to – especially in this current season.
The Greek word for be on guard is blepō; it means: “to look at (literally or figuratively); metaphorically, to see with the mind’s eye; to turn the thoughts or direct the mind to a thing, to consider, contemplate, look to; take heed; to look to oneself.” (Mark 13:5, 9, 23, 33)
The Greek word for keep watch (be on alert) is grēgoreō: “to keep awake, i.e. watch (literally or figuratively); metaphorically, to watch, i.e. give strict attention to, be cautious, active.” (Mark 13:34, 35, 37; 14:34, 37, 38)
We’re called to be on guard and to be alert. To look and watch. To see and stay awake. To contemplate and be cautious.
We have an enemy we’re to stand firm against, though he’s not flesh and blood (Ephesians 6:10-13). We are not to be ignorant or unaware of his schemes (2 Corinthians 2:11).
Grēgoreō is also used in 1 Peter 5:8 for “be alert” (verses 7-9 shared for context): “Cast all your anxiety on him because He cares for you. Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour. Resist him, standing firm in the faith, because you know that the family of believers throughout the world is undergoing the same kind of sufferings.”
I appreciate how this passage sums it up: God cares for you; He can handle what you’re going through. Be mindful of the enemy, but not obsessed. Jesus has already defeated him, so stand firm. You’re not alone in your suffering.
A side note, as noticed in my healing journey: I would propose that these biblical phrases of being on guard and keeping watch are different than hypervigilance and a dysregulated nervous system. I think we can be on guard and alert in ways that Jesus commanded that don’t negatively affect our mental health.
There’s one more phrase that I love from Mark 14:8 that I’ll leave you with: “She did what she could.” And Jesus called it beautiful.
Selah.
