Jeremiah 17:5 describes what happens when a human being becomes the structural foundation of your emotional world: "Cursed be the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD." The word "arm" — zeroa' — is the Hebrew metaphor for the thing you lean on, the structural support of your weight. Building your emotional stability on another human being is not loving them better. It is asking them to hold a weight only God was designed to bear.
Psalm 62:1 offers the alternative interior posture: "Truly my soul waiteth upon God: from him cometh my salvation." The Hebrew damah — "waiteth" — carries the sense of being still, being silent before something, resting in expectation. The soul that waits on God has its primary orientation toward something that will not shift. This is the interior condition that makes healthy love of another person possible — love that does not require the other person to be your stability.
