What does the Bible teach about human sinfulness?

Throughout scripture, from the faith of Abraham to the weaknesses of even the best saints, the truth is clear: we are all sinful men and women in need of a Savior. The Bible does not hide these realities but shows them to remind us of our depravity and dependence on Christ. Passages like Romans 3:23 remind us that all have sinned and fall short of the glory of God. This depiction of human sinfulness serves multiple purposes—it emphasizes our need for grace, highlights the righteousness of Christ as our only hope, and continually directs our reliance on Him as we navigate our Christian walk.
