Lesson 7 – Mankind Dead In Sins

When man became dead in sins, every part of him was affected. Therefore, there is no part of man that is able to respond to God while man is in this condition of being dead in sin. There is no good left in man — not even a slight spark. Sin has affected every faculty of man’s being just as a drop of poison would affect every molecule of a glass of water. Sin has stained every faculty in man, and thus it affects his every act.

An examination of the Scriptures will abundantly show that sin has warped every faculty in man:

Romans 8:7 The mind is depraved.

Jeremiah 17:9 The heart is depraved.

John 3:19 Man is depraved in his affections or desires.

Titus 1:15 The conscience is depraved.

Psalm 58:3 & Romans 3:13 The speech is depraved.

Romans 3:15 Even the feet are depraved.

Romans 3:10-19 & Isaiah 1:5-6 Man is depraved from head to foot.

Because man is thus totally depraved or completely dead in trespasses and sins, he cannot, until quickened by the Spirit of God, turn from sin to God in Godly repentance and faith (Jeremiah 13:23; John 6:44,65; John 12:39-40).

This doctrine that we have been studying has sometimes been called the doctrine of Total Depravity or Total Inability.


1. Is the expression “let your conscience be your guide” a safe one to go by? Why or why not?

2. Since the heart is deceitful, what is the only safe guide we can use to govern our lives by?

3. Why did the chief priests and Pharisees want to kill both Jesus and Lazarus, even though they knew that Jesus had raised Lazarus from the dead? (John 11:47-53 & John 12:10-11; Acts 4:16-17)

4. Why will the world experience trouble and bloodshed until the Lord Jesus Christ returns?

Memory Verse:

We have memorized Romans 5:12; Psalm 51:5; I Corinthians 2:14; Ephesians 2:1; Romans 3:23; and John 8:47.

For our last verse on this subject let us memorize Romans 3:10. This will give us seven basic Scriptures on this subject which will enable us to witness to others and to defend this Scripture truth.
