What does the Bible say about human strength?

Throughout scripture, we see consistent testimony about human weakness and inability. For example, the experiences of figures like Daniel, Isaiah, Job, and Paul illustrate that true strength comes from God alone. When each of these individuals encountered God's holiness, they were struck by their own inadequacies, revealing the vast divide between humanity and the Almighty. This core principle of dependence on God highlights the importance of grace in salvation; it is He who empowers us, not our own efforts.
