The relationship between a person and God is built on a mutual foundation of deep longing and divine support. On one side is the soul's intense craving for closeness to the Creator, and on the other is the heavenly assistance that either makes this connection possible or rewards it. This yearning takes the form of an exclusive love, a desire to follow God constantly without any separation [אבן עזרא, מאירי, ביאור שטיינזלץ]. It also takes practical shape through uninterrupted devotion to studying and fulfilling the teachings of the Torah [חומת אנך].
There are different ways to understand how human devotion interacts with God's support. One perspective views God's support as a direct reward and a source of physical protection. Because a person chooses to remain close to God, God takes hold of him, guarding him from stumbling and protecting him from enemies who pursue him [רש״י, רד״ק, מצודת דוד].
Conversely, another approach views this divine support not merely as a reward, but as the essential spiritual assistance that makes the connection possible in the first place. A person does not have the natural strength on his own to stay close to God or to overcome his negative impulses. He only succeeds because God actively helps and supports him [אבן עזרא, חומת אנך]. In this light, God's supporting hand is also seen as a representation of the Torah itself. The Torah protects a person from sin, and the act of engaging with it cancels the threats of those who wish him harm [חומת אנך].
A deeper layer of understanding focuses on the tension between the physical body and the spiritual soul during moments of intense divine closeness. When the soul craves God with immense power, it naturally wishes to escape the physical body to merge completely with Him. In this context, God's support is a unique act of kindness. He pours holiness directly into the physical flesh, granting the body the strength to contain the overwhelming intensity of the soul. It is only through this divine support that the soul can remain within a living person, rather than leaving the body behind out of pure, overwhelming devotion [אלשיך].
