What does the Bible say about being ruined by sin?

According to the Scriptures, particularly Titus 3:3, we are all described as foolish and disobedient, lost in our sins. Genesis 6:5 reinforces this understanding, stating that the wickedness of man is great and every thought of their hearts is only evil continually. We cannot, by our own efforts or moral righteousness, make things right with God. The reality of our condition is further emphasized in Jeremiah 17:9, which declares that the heart is deceitful and desperately wicked. Without acknowledging our ruined state, we cannot understand the need for a Savior.
