can we "lose" our salvation?

Somebody just emailed me asking me “Can a true believer lose their salvation?”  

Here’s my response:

nope

Why?
Because using the word “loose” it is implied that something is accidentally lost.  ie “I lost my keys” (meaning I wish I had them, but I accidently lost them /i cannot find them…)
or “I lost my wife at the mall because she refuses to use her MOBILE phone!” =) 
But if your question in fact is this “Can a true believer give up their salvation?”  The answer is yes
2 ways:
 by making an emphatic choice to do so  ie “I no longer choose to serve God and accept Jesus as my atonment - as the one who died for my sins…”
or by over time, consistently making choices that go knowingly do not please God or align with His Word.
Making daily choices to ignore God’s Holy Spirit (His voice to us now) and making choices to ignore His Word on a daily basis clearly tells God “I am no longer following you; I have 
chosen to follow my selfish ways and live life apart from your guidance…" 
Ross, make sense?
now here’s a TON of scripture to back up what I’ve said:

2 Peter 2:17-22

17 These people are as useless as dried-up springs of water or as clouds blown away by the wind — promising much and delivering nothing. They are doomed to blackest darkness. 18 They brag about themselves with empty, foolish boasting. With lustful desire as their bait, they lure back into sin those who have just escaped from such wicked living. 19 They promise freedom, but they themselves are slaves to sin and corruption. For you are a slave to whatever controls you. 20 And when people escape from the wicked ways of the world by learning about our Lord and Savior Jesus Christ and then get tangled up with sin and become its slave again, they are worse off than before. 21 It would be better if they had never known the right way to live than to know it and then reject the holy commandments that were given to them. 22 They make these proverbs come true: "A dog returns to its vomit,” and “A washed pig returns to the mud."   NLT

Matt 6:14-15

14 "If you forgive those who sin against you, your heavenly Father will forgive you.  15 But if you refuse to forgive others, your Father will not forgive your sins.”  NLT

Jesus said as recorded in Matt 10:22-23  “But those who endure to the end will be saved.”  NLT

Implying that there are those who will not endure – those who will give up on their faith in Christ.  Jesus made it plain and simple that the “race that God sets before us” is a race of endurance, not a quick sprint.  We must allow God to give us the strength to preserve through anything and endure until the end of our life.  Only then, will we be saved from sin. 

So “let us take off every weight that slows us down, especially the sin that so easily hinders our progress. And let us run with endurance the race that God has set before us. 2 We do this by keeping our eyes on Jesus, on whom our faith depends from start to finish.” Heb. 12:1-2

 

2 Tim 2:11-12  “This is a true saying: If we die with Him, we will also live with Him.  12 If we endure                                 hardship, we will reign with Him.  If we deny Him, He will deny us.”  NLT

 

Rom 5:3-5  3 “We can rejoice, too, when we run into problems and trials, for we know that they are good for us — they help us learn to endure. 4 And endurance develops strength of character in us, and character strengthens our confident expectation of salvation. 5 And this expectation will not disappoint us. For we know how dearly God loves us, because he has given us the Holy Spirit to fill our hearts with His love.”  NLT

Heb 6:1-6  “So let us stop going over the basics of Christianity again and again. Let us go on instead and become mature in our understanding. Surely we don’t need to start all over again with the importance of turning away from evil deeds and placing our faith in God. 2 You don’t need further instruction about baptisms, the laying on of hands, the resurrection of the dead, and eternal judgment. 3 And so, God willing, we will move forward to further understanding.  4 For it is impossible to restore to repentance those who were once enlightened — those who have experienced the good things of heaven and shared in the Holy Spirit, 5 who have tasted the goodness of the word of God and the power of the age to come —  6 and who then turn away from God. It is impossible to bring such people to repentance again because they are nailing the Son of God to the cross again by rejecting Him, holding Him up to public shame.”  NLT

Matt 7:21-25  "Not all people who sound religious are really godly. They may refer to me as ‘Lord,’ but they still won’t enter the Kingdom of Heaven. The decisive issue is whether they obey my Father in heaven.  22 On judgment day many will tell me, 'Lord, Lord, we prophesied in your name and cast out demons in your name and performed many miracles in your name.'  23 But I will reply, 'I never knew you. Go away; the things you did were unauthorized.'  24 "Anyone who listens to my teaching and obeys me is wise, like a person who builds a house on solid rock.”  NLT
