The nature of the heart of man may be different than we believe it to be. The Bible teaches us that we must be aware of the evil impulses that the heart is prone to. This is very important because the heart in the Bible refers to the inner nature of our character. To overcome the deception and evil that may be in our heart, we need to rely on God to examine and expose our weaknesses. Only by coming to God with a broken heart can we live a life that is pleasing to Him.
