We believe that after the fall man lost his exalted position before God. Since then, all mankind has been under sin with its results. Man is born with weakness and a tendency to evil and is subject to the power of death.

“His nature became so weakened through transgression that it was impossible for him, in his own strength, to resist the power of evil.

“In the apostasy, man alienated himself from God; earth was cut off from heaven. Across the gulf that lay between, there could be no communion.” – Steps to Christ, pp. 17, 20.

“When man transgressed the divine law, his nature became evil,.” – The Great Controversy, p. 505.

“Man had become so degraded by sin that it was impossible for him, in himself, to come into harmony with Him whose nature is purity and goodness.” – Patriarchs and Prophets, p. 64.

This is how mankind’s situation became hopeless.
Romans 5:12 – 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:
Romans 3:10-12 – 
As it is written, There is none righteous, no, not one: There is none that understandeth, there is none that seeketh after God. They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one. 
Romans 6:23 – 
For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
Psalm 51:5 – 
Behold, I was shapen in iniquity; and in sin did my mother conceive me. 
Matthew 15:18-20 – 
But those things which proceed out of the mouth come forth from the heart; and they defile the man. For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies.These are the things which defile a man: but to eat with unwashen hands defileth not a man. 
Galatians 5:19-21 – 
Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God. 
Romans 7:18-20 – 
For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. For the good that I would I do not: but the evil which I would not, that I do. Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
