The sermon explores the foundational aspects of understanding God, emphasizing that He is the creator of all things, inherently holy and just, and ultimately defined by steadfast love. It challenges listeners to confront the reality of God's holiness and justice, contrasting it with human tendencies to suppress truth and seek mercy, while highlighting the importance of recognizing God's character as surpassing human imagination. The sermon encourages a shift from personal conceptions of God to a reliance on biblical teachings, ultimately inviting listeners to engage with a God who is both powerful and compassionate, and to consider the implications of encountering God as he has revealed himself in Scripture rather than how we like to think of him.
