Who Am I and Why Do I Matter? Chapel Recap on Psalm 139 With Alistair Begg.

Today in chapel, Alistair Begg opened with the questions, “Who am I, and why do I matter?” He turned to Psalm 139 for the answers, reminding us that our identity and worth are rooted in the God who knows us completely.

In verses 1–6, David reminds us that God truly knows us. Begg emphasized that the same God who formed the ear, the eye, and the mind is the God who hears, sees, and knows everything. God knows our movements and our thoughts even before they take form. There is no corner of our lives hidden from Him. As Alistair Begg put it, “I cannot hide anything from a God whose knowledge of me is so wonderful.” God is not distant — He is personal.

In verses 7–12, David shifts to explain that God is with us. We cannot outrun His presence, nor can we out-sin His grace. David discovered that the only true shelter is found in the God who goes before us and comes behind us. Begg then explains that learning that God knows us this personally is not a burden or a restriction but a privilege.

However, this truth collides with three of the biggest lies of our culture:

1. There is no Creator God.
2. There is no absolute morality.
3. There is no ultimate truth.

If those lies are true, then the question “Who am I?” has no clear answer. But Scripture reveals the truth.

David’s reflection in Psalm 139 and Begg’s challenges lead us back to where we must begin: God sees, God hears, and God knows. This reality draws us into hope, for the subtlety of sin lies in self-deception, but the security of faith lies in being fully known and fully loved by a personal God.
