Numbers 10:10 says to “blow the bugles…; they will keep your attention on God”
Every waking moment is spent focusing on something–even when daydreaming! Focus can be undisciplined (roaming from one target to another) or disciplined (actually choosing priorities as targets). It’s so easy to shift that attention to personal pain/issues or reacting to someone else’s comments/decisions or anything but what our #1 focus should be in this life: God.
I think bugles in our lives are people who give us godly advice from the outpouring of their walk with God, and bugles are habits/thought patterns that regularly drive thoughts to Him.
