What is the state of man?

Genesis 1:27

27 So God created man in his own image,
    in the image of God he created him;
    male and female he created them.

Romans 5:12,19

12 Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men[e] because all sinned— 

19 For as by the one man's disobedience the many were made sinners, so by the one man's obedience the many will be made righteous.

Mankind was made in the image of God. Meaning they were made to reflect, in a limited and finite way, the character of God. In addition, mankind was created to fellowship with the Triune God. However, Adam transgressed the covenant of works. Adam broke the one command God gave him in the Garden (Genesis 2:16-17) which brought spiritual death and physical death to him and all his descendants (us).

All mankind comes forth from Adam and is held guilty by God of Adam’s transgression (Romans 5:12). Not only that, all of mankind inherits Adam's sin nature. Our faculty of choice, the will, is in bondage to our sinful natures. Paul describes the state of fallen mankind as dead in our trespasses, following the prince of the power of the air, living in the passions of our flesh (Ephesians 2:1-3).

Mankind’s will can freely choose horizontal things such as where to go to eat, whether to go to the gym to workout, when to call someone, etc. However, mankind cannot choose God vertically because our will is in bondage to our own sin nature. There is nothing good in mankind that can respond to God.  John 3:20 states, “20 For everyone who does wicked things hates the light and does not come to the light, lest his works should be exposed.”

All mankind belongs to Adam naturally in their birth and only those born again (born of the Holy Spirit per Titus 3:3-8, Ephesians 2:1-4, John 3:1-15) belong to the Lord Jesus who gives them life, righteousness, and justification (Romans 5:15-21). For the Lord Jesus is the only hope of Adam's seed.
