The imagery of Jeshurun growing fat and kicking is a vivid portrayal of Israel's prosperity leading to spiritual complacency. Jeshurun, meaning 'upright one,' is a symbolic name for Israel, highlighting their initial righteousness. However, as they became prosperous, they turned away from God, forgetting the source of their blessings. This verse warns against the dangers of allowing material wealth and comfort to lead to spiritual neglect and ingratitude.
The phrase 'abandoned the God who made them' underscores the seriousness of their actions. It emphasizes the importance of remembering and honoring God, especially in times of abundance. The 'Rock their Savior' refers to God's steadfastness and reliability, contrasting with the people's fickle nature. This serves as a timeless reminder for believers to remain grounded in their faith, regardless of their circumstances, and to continually acknowledge and rely on God's guidance and provision.
