What does the Bible teach about human limitations?

In Ecclesiastes 1:15, Solomon states, 'That which is crooked cannot be made straight; and that which is wanting cannot be numbered.' This reflects the Reformed doctrine of total depravity, where human beings, marred by sin, lack the capability to rectify their own spiritual condition or the brokenness of the world. This principle serves as a reminder to Christians that they should rely on God's grace rather than their own understanding or efforts. It also points to the ultimate hope found in Christ, who alone can restore and redeem what is crooked. The acknowledgment of human limitations urges believers to seek divine intervention and rely on the transformative power of God’s grace.
