Will suicide keep me out of Heaven?

Would someone want to kill themselves if they had the hope and love of Christ in their heart? Suicide is most commonly a result of hopelessness. Suicide is only self-serving. Suicide is the act of ending one's own life because that circumstances or emotions are overwhelming to the point of despair. Such despair cannot exist in a heart filled with the love of God and the hope of eternity with Him.

The taking on of the responsibility of one's own life and choosing to end it bears no regard to the consequences that the action will have on the living. Such selfishness is rejected by God:

People will be lovers of themselves, lovers of money, boastful, proud, abusive, disobedient to their parents, ungrateful, unholy, without love, unforgiving, slanderous, without self-control, brutal, not lovers of the good, treacherous, rash, conceited, lovers of pleasure rather than lovers of God — having a form of godliness but denying its power. Have nothing to do with them. They are the kind who worm their way into homes and gain control over weak-willed women, who are loaded down with sins and are swayed by all kinds of evil desires, always learning but never able to acknowledge the truth. Just as Jannes and Jambres opposed Moses, so also these men oppose the truth — men of depraved minds, who, as far as the faith is concerned, are rejected. -- 2 Timothy 3:2-8 (NIV)

I believe that most of the excuses anyone would use for committing suicide are covered in that passage.

A couple additional points that I did not see here are that in committing suicide:

• This would prevent us from gaining many of the rewards we could earn in Heaven through the good works we could do on earth.

Matthew 16:27 (NKJV) “For the Son of Man will come in the glory of His Father with His angels, and then He will reward each according to his works.

• This would possibly prevent other people from coming to know Jesus as their Savior (e.g. you would loose the opportunity to witness to others).

Those of us who are saved will be rewarded for the good things we have done here. If we kill ourselves, we rob ourselves of the opportunity to gain more reward in Heaven because we take away the time we have to do good works. We would also remove ourselves from the opportunity of bringing others to know Him. I want to stay here until He takes me to Heaven so I can earn more rewards in Heaven and witness to other people, and even enjoy the good things God has given in this life.

While I don't believe committing suicide excludes you from heaven, I do believe it's a sin (and one you can't repent from):

James 3:16 (NIV)

16 For where you have envy and selfish ambition, there you find disorder and every evil practice.

What could be more selfish than learning about (and accepting) God's gift and then killing yourself without sharing that?

1 Corinthians 13:13 (NIV)

13 And now these three remain: faith, hope and love. But the greatest of these is love.

What love are you sharing if you commit suicide, leaving behind people who love you in sorrow?

Edit

It also might be important to keep 2 Corinthians 5:10 (NIV) in mind:

10 For we must all appear before the judgment seat of Christ, so that each of us may receive what is due us for the things done while in the body, whether good or bad.

So even though we are all forgiven (and since we're assuming the person committing suicide has accepted the Jesus as savior), there is still the judgment everyone will face for all their deeds.

There are some great answers and comments on this question, and I'd like to try and add in on it: No, suicide does not automatically damn you to hell. If you are born again in Christ, all your sins are washed clean, even ones you have not yet committed. If they weren't, then somehow Christ's death on the cross was incomplete. His sacrifice is eternal, the living sacrifice, thus your salvation and redemption is eternal.

I see some people have said that suicide is the result of mental illness, depression, etc. When I was young in my faith, I contemplated suicide a couple times for the exact reason mentioned by OP. I wasn't mentally ill; I just wanted to be in heaven! Some people have also said suicide for this reason might reveal a lack of faith, but how could you have what it takes to off yourself (to simply go to heaven early) if you have no faith in heaven/Christ? Anyway, that's not important. I think what's important is the response to

Strictly speaking in a logical sense this is the best thing a person could do for themselves.

We must see that is extremely selfish. Do you not know that Jesus came to this earth to live, suffer and die for you? Then should you not live and, if needed, suffer and die for Him too? We are meant to be vessels of God, fit for his work (2 Tim 2:21, Rom 9:23-24, 2 Cor 4:7). If you take your life then you are taking away any possible plan that God has prepared for you. Would you expect to hear "Well done, good and faithful servant!" after that? I sure wouldn't. I would have an eternity of shame ahead of me.

Look forward to the life God has in store for you, or if he takes you home early, then know it was of divine purpose and not your own selfish will. If you have a mind set on heaven so much that you just want to be there right now, then use that mindset to be as close to God as you can and fulfill His purposes in your life (1 John 2:17), in this lifetime now.

If suicide excluded someone from going to heaven, then Jesus words in John 3.16 would not be true:

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.

Yes, I accept that suicide would lead one to question the individual's faith, and possibly even make a decision that the said person was not truly a Christian. We cannot know for sure what God's perspective on that individual is.

Even very damaged and broken people who have had a terrible life can come to Jesus. Faith in Christ does not immediately make an abused person who has a very poor self image suddenly "well" again, nor is it a guarantee that it they would free them from depression.

There are a couple issues here.

First:

Strictly speaking in a logical sense this is the best thing a person could do for themself.

No. Suicide is never a logical solution to any situation. If anyone is in a position where they think it is, they would be best served by taking a time out and then seeking help.

But this question is not really about suicide.

The Premise

1. Perhaps the greatest thing a person can hope for is to enter the Kingdom of Heaven.
2. We are told that if a person truly accepts God as their Saviour, they promised an eternity in heaven.

With this in mind, why not just accept Christ and then off ourself? We all want to go to heaven don't we?

The biggest problem with this logic is its premise, the characterization of Christianity as nothing more than accept Christ as your savior so you can go to heaven.

The Cost

Nowhere in the New Testament does it say it is enough to "just accept Christ". Rather, when Jesus called his disciples, he told them to follow him. In the case of four fishermen (see Matthew 4:18-22) this meant leaving behind their boats and nets, their entire way of life, and even their families. Following Jesus meant abandoning everything that came before and starting a whole new way of life.

Jesus alludes to this in Luke 14:27-28.

Whoever does not carry the cross and follow me cannot be my disciple. For which of you, intending to build a tower, does not first sit down and estimate the cost, to see whether he has enough to complete it?

There is a cost to following Christ, and the cost is abandoning our own willfulness and sinfulness. We must give up everything that stands in the way of following him.

For a wealthy tax collector named Zacchaeus, it meant paying back those whom he had cheated. For another rich man, the cost was too high. For the apostle Paul, it meant giving up his claims to righteousness, and indeed, everything that had been his identity.

The point is, once we make the decision to, as they say, "accept Christ", our life is no longer our own. It's all about what God wants for us, and not about what we want.

The Reward

Jesus expresses this as a paradox in Matthew 10:39.

Those who find their life will lose it, and those who lose their life for my sake will find it.

He's not talking (here) about literally losing our lives. He's not asking us to "off ourselves". He's talking about changing our very identity. This is known as sanctification.

Our human nature is sinful, bent to our own desires, but when God sanctifies us we live for his desires and not our own. And God does not want us to escape this world (John 17:15-17), but rather to let God complete the transformation (2 Corinthians 3:18), and possibly help others in their transformation as well.

The apostle Paul wrestled with this while he was in prison awaiting trial, not knowing whether he would be put to death or released (Philippians 1:21-24). (Thanks to Jon Ericson for this reference.)

For to me, living is Christ and dying is gain. If I am to live in the flesh, that means fruitful labor for me; and I do not know which I prefer. I am hard pressed between the two: my desire is to depart and be with Christ, for that is far better; but to remain in the flesh is more necessary for you.

And that's why we can't "just accept Christ and then off ourself [sic]". Even if we may want to skip the hardship and go to heaven right away, becoming a Christian means giving up what we want and giving in to what God wants.
