Sin and Man's Nature
1 Peter 1:24 – 25 - "For all flesh is as grass, and all the glory of man as the flower of grass. The grass withereth, and the flower thereof falleth away: But the word of the Lord endureth for ever. And this is the word which by the gospel is preached unto you."
We understand from the Word of God that we, as mankind, are born into this world as sinners due to the sin of our first parents Adam and Eve. Ever since they turned from believing the word that God had spoken to them and rebelled against His authority, death has passed upon all men through their disobedience. Man in his natural state is a sinner from conception (Psalm 51:5), is powerless to change his own nature ( Romans 8:7), and there is not one man who is able to stand before God as justified by his own works (Romans 3:20).
The Scripture uses words like “bondage”, “captivity”, and “dead” to describe the helplessness of man’s condition. Since we are all born in the image of Adam, who was our first father, we all bear the same nature within us that he had. Romans 5:12 speaks of it this way “Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:”
Consequently, we know that when it comes to our position before God, we are all guilty (Galatians 3:22), and wholly unable to overcome our own nature. This is our natural state as we are born into the world, and includes all who are born into this life (Romans 3:10-12).
