Maybe we're just on different wavelengths, but I have a difficulty reconciling that with a number of Biblical teachings such as the fifth petition of the Lords Prayer which seems to pet our forgiveness on our forgiveness of others (something we must do) and the admonition to remain faithful to the end to be saved (again something we must actively do to be saved).
If you are of a mind that God does this for us and we don't have any part to play in it we are of a different mind, something that, as Christians, we need to work on. I take things like this very seriously as Corinthians 1:10 tells us we should and believe different Christians and different denominations not being of the same mind, not even of the same mind with each other within those denominations, is why the Church and Christians today have no real power, remember that Jesus told us we can do the same things he did but no one today seems to be able to do that.
The Lord's Prayer does not say that we don't have salvation if we don't forgive others.
And forgive us our trespasses,
As we forgive those who trespass against us.
You've added something into the text that just isn't there. It indicates that as believers, we are to forgive others, but there is no condition saying that if we don't forgive that we're hellbound. That goes against the Gospel itself of forgiveness won at the cross for our sins! The sin of not being able to forgive someone was forgiven, so your point doesn't work according to the Gospel.
1 Corinthians 1:10 I appeal to you, brothers and sisters, in the name of our Lord Jesus Christ, that all of you agree with one another in what you say and that there be no divisions among you, but that you be perfectly united in mind and thought.
There were divisions from the beginning and will be until the end and that is because the Holy Spirit is working in us to perfect our faith.
God saves you. You do nothing because you cannot do it, that's why Christ came to die for you in your place.
