What is it about universal redemption that annoys so many Christians?
It doesn't annoy me; it puzzles me why anyone teaches it.
There are a number of teachings that we should repent now, while we can. Why would Jesus have taught that if the truth was "live as you like, you'll be saved in the end"?
Shouldn’t we be happy that God’s love and mercy are wider, higher, deeper, and broader than we could ever imagine?
It is.
His love is so great that he will not force anyone to believe in, and love, him.
We all sin at times so shouldn't we welcome the thought that God is not going to annihilate or eternally torment us if we don't “accept,” “trust,” “repent,” “believe,” well enough to appropriate the grace of God?
Only faith the size of a mustard seed is needed.
If someone says, "will you accept Jesus?" or if he himself were to say that; all that's needed is the word "yes". Faith and understanding don't come all at once, but once we belong to Jesus he will never let us go and no one can snatch us from his hands.
We don't need to, and can't, "do enough to appropriate the grace of God" - it is there for all; waiting for a response.
Here are some of the reasons that have been expressed in the threads:
1. ”If everyone is or will be saved, what’s the point in following Jesus?”
To me, anyone who thinks this must see following Jesus as a heavy burden,
Not necessarily.
But Jesus says "repent, believe in me and have eternal life". The Bible says that those who do not have eternal life will perish, John 3:16, John 3:36, 1 John 5:12 - why would it say that if in fact it meant, "don't worry if you don't want to believe in Jesus now; you'll still be saved one day"?
It's not so much "why follow Jesus?" but "why would Jesus have told people to repent and have eternal life now", if it isn't necessary? He said to the rich man, "you fool; this night your soul will be required of you"; not "well it was a waste of time hoarding money, but you will be saved anyway."
It's also a misunderstanding of Christian Universalism to think it says that we don't have to receive the saving grace of Christ in order to be reconciled to God and to each other. It just says that if we don't manage to do this in this life there will be boundless opportunities to do so in the next one and that eventually every one will accept forgiveness and repent of their sins...
"If we don't MANAGE to receive God's grace in this life", implies, to me, that there has not been the chance to receive it - the Gospel hasn't been preached, or fully understood. God would know and understand if that had been the case and would, imo, judge accordingly.
That is not at all the same as saying, "I reject God, I'm not going to accept him or think about him now; he will save me/give me another chance after death because he is love".
”that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth" (Phil 2:10)
Everyone will see, and recognise, Jesus; even those who rejected him in this life. That doesn't mean they will be able to repent and be saved.
Imo, that's what hell will be - knowing without a shadow of a doubt that Jesus died for your sins, but also knowing that you rejected that forgiveness when it was offered, and it is now too late. Knowing that Jesus is Lord and that all honour and glory is due to him; the one that you hated/rejected.
3. ”If there is an 'us,' there has to be a 'them'"
This may be true about some things such as football: I support Manchester United so I hate Manchester City (I'm from the UK, apologies) but it needn't apply to matters of faith. If we are going to heaven when we die there doesn't have to be a group who go to hell.
Except that the NT says otherwise.
In the NT, you are for Jesus, or against him; in the light or in the darkness; have eternal life, or don't. Those who reject God's amazing, free gift of eternal life, Romans 6:23, cannot live with him when they die. If people die in their sins, with unforgiven sin, how and why would a Holy God say "it's fine; be saved and come and live with me forever anyway"?
There are biblical arguments that can be made for and against Christian Universalism
I can't see any for it - repent, receive eternal life or perish, seems pretty clear to me.
The question about God saving people who never get to hear the Gospel, or who are unable to accept it, is a different one. There ARE arguments for saying "God will save the anyway, even if they haven't heard." But that is not what I understand by universalism. Universalism says that everyone will be saved - even if they have wilfully and continually chosen to reject God's Son and gift of eternal life.
For me, it's basically relief that God is a loving God and not a monster after all.
"Not a monster,
after all" suggests that you have thought/been taught that he is - maybe because someone has said that he
sends people to hell to be punished. Maybe you have grown up with images of a God who tortures people for not believing in him; pushing them, happily, towards an eternal barbecue.
He doesn't.
He has sent Jesus, given us the Gospel and the choice of whether or not to receive his free gift of life. If someone, deliberately and continually says "no" to God, knowing who he is and what they are rejecting, how would it be loving to force them to spend eternity with him when they die?
