Can a Christian forfeit his/her salvation? -- (1)

(1)    Man’s plight:

Genesis 6:5

The Lord saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time.

Romans 6:23

For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.

Romans 3: 10 – 24

As it is written:  “There is no one righteous, not even one; there is no one who understands; there is no one who seeks God.  All have turned away, they have together become worthless; there is no one who does good, not even one.”  “Their throats are open graves; their tongues practice deceit.”  “The poison of vipers is on their lips.”  “Their mouths are full of cursing and bitterness.”  “Their feet are swift to shed blood; ruin and misery mark their ways, and the way of peace they do not know.”   “There is no fear of God before their eyes.”  Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God.  Therefore no one will be declared righteous in God’s sight by the works of the law; rather, through the law we become conscious of our sin.  But now apart from the law the righteousness of God has been made known, to which the Law and the Prophets testify.  This righteousness is given through faith in Jesus Christ to all who believe. There is no difference between Jew and Gentile, for all have sinned and fall short of the glory of God,  and all are justified freely by his grace through the redemption that came by Christ Jesus.

John 3:16 – 19

For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.  For God did not send his Son into the world to condemn the world, but to save the world through him.  Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son.  This is the verdict: Light has come into the world, but people loved darkness instead of light because their deeds were evil.
