12 Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all men, because all sinned—
13 for before the law was given, sin was in the world. But sin is not taken into account when there is no law.
14 Nevertheless, death reigned from the time of Adam to the time of Moses, even over those who did not sin by breaking a command, as did Adam, who was a pattern of the one to come.
Romans 5:12-14 (NIV)
What is this death?
Physical death
4 My guilt has overwhelmed me like a burden too heavy to bear.
5 My wounds fester and are loathsome because of my sinful folly.
6 I am bowed down and brought very low; all day long I go about mourning.
7 My back is filled with searing pain; there is no health in my body.
8 I am feeble and utterly crushed; I groan in anguish of heart.
Psalm 38:4-8 (NIV)
Emotional death
7 For God has not given us a spirit of fear and timidity, but of power, love, and self-discipline.
2 Timothy 1:7 (NLT)
Nothing destroys relationships between people greater than sin
Planetary death
18 I consider that our present sufferings are not worth comparing with the glory that will be revealed in us.
19 The creation waits in eager expectation for the sons of God to be revealed.
20 For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope
21 that the creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God.
Romans 8:18-21 (NIV)
Spiritual death
18 They are darkened in their understanding and separated from the life of God because of the ignorance that is in them due to the hardening of their hearts.
19 Having lost all sensitivity, they have given themselves over to sensuality so as to indulge in every kind of impurity, with a continual lust for more.
Ephesians 4:18-19 (NIV)
10 When he died, he died once to break the power of sin. But now that he lives, he lives for the glory of God.
11 So you also should consider yourselves to be dead to the power of sin and alive to God through Christ Jesus.
Romans 6:10-11(NIV)
