Harold Camping has been wrong before. The sign of a TRUE prophet is that EVERY prophesy he makes comes to pass.
Deuteronomy 18:22
If what a prophet proclaims in the name of the LORD does not take place or come true, that is a message the LORD has not spoken. That prophet has spoken presumptuously. Do not be afraid of him.
Matthew 24:36-39
36"No one knows about that day or hour, not even the angels in heaven, nor the Son,[f] but only the Father. 37As it was in the days of Noah, so it will be at the coming of the Son of Man. 38For in the days before the flood, people were eating and drinking, marrying and giving in marriage, up to the day Noah entered the ark; 39and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man.
Mark 13: 32-37
32"No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father. 33Be on guard! Be alert[f]! You do not know when that time will come. 34It's like a man going away: He leaves his house and puts his servants in charge, each with his assigned task, and tells the one at the door to keep watch.
35"Therefore keep watch because you do not know when the owner of the house will come back—whether in the evening, or at midnight, or when the rooster crows, or at dawn. 36If he comes suddenly, do not let him find you sleeping. 37What I say to you, I say to everyone: 'Watch!' "
We are to watch, but to presume to know something that not even Jesus or the angels know is bordering on blasphemy. I have a friend that listens to Harold Camping "religiously" and is convinced that the end of the world is May of 2011.
Don't worry about when the world is going to end, just be sure that you know where you are going when it does end. Eternity if a long time and I for one want to be sure where I'm spending it.
1 John 5
Faith in the Son of God
1Everyone who believes that Jesus is the Christ is born of God, and everyone who loves the father loves his child as well. 2This is how WEKNOW that we love the children of God: by loving God and carrying out his commands. 3This is love for God: to obey his commands. And his commands are not burdensome, 4for everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith. 5Who is it that overcomes the world? Only he who believes that Jesus is the Son of God.
6This is the one who came by water and blood—Jesus Christ. He did not come by water only, but by water and blood. And it is the Spirit who testifies, because the Spirit is the truth. 7For there are three that testify: 8the[a] Spirit, the water and the blood; and the three are in agreement. 9We accept man's testimony, but God's testimony is greater because it is the testimony of God, which he has given about his Son. 10Anyone who believes in the Son of God has this testimony in his heart. Anyone who does not believe God has made him out to be a liar, because he has not believed the testimony God has given about his Son. 11And this is the testimony: God has given us eternal life, and this life is in his Son. 12He who has the Son has life; he who does not have the Son of God does not have life.
Concluding Remarks
13I write these things to you who believe in the name of the Son of God so THAT YOU MAY KNOW THAT YOU HAVE ETERNAL LIFE. 14This is the confidence we have in approaching God: that if we ask anything according to his will, he hears us. 15And if we know that he hears us—whatever we ask—we know that we have what we asked of him.
16If anyone sees his brother commit a sin that does not lead to death, he should pray and God will give him life. I refer to those whose sin does not lead to death. There is a sin that leads to death. I am not saying that he should pray about that. 17All wrongdoing is sin, and there is sin that does not lead to death.
18We know that anyone born of God does not continue to sin; the one who was born of God keeps him safe, and the evil one cannot harm him. 19We know that we are children of God, and that the whole world is under the control of the evil one. 20We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true—even in his Son Jesus Christ. He is the true God and eternal life.
