From Genesis to Revelation, God regularly expressed his consistent view about the nature of mankind. In Genesis, even after the flood, God recognised that "every intent of the thoughts of his heart was only evil continually". This is repeated in Jeremiah, in Psalm 14, and in Romans 3, with specific descriptions, the end result is the same... we are not able to obey the law, and not able to gain salvation by ourselves. But God promised to find a way, and we know that Jesus' sacrifice is that way. We must humbly acknowledge that we are human, and must turn to Jesus for our salvation.
