How can a loving God send people to hell?

God’s goodness is evident not just in extreme love, but extreme justice. Since all of us have rebelled against God, he is just in giving us the punishment that we deserve. We live as if we want little to do with God, and the punishment we face is just that - eternal separation from him in a reality Jesus called hell. This will not be the same experience for all, but will somehow be proportionate to the wrong they've done. Nevertheless, it will be terrible for everyone there. Yet hell is a good thing, as it ensures that those who get away with awful things now will be brought to account, and it will show their victims just how seriously God took what was done to them.

Thankfully, in love God has enabled us to escape this awful reality. He sent his Son Jesus to bear this punishment on our behalf, experiencing the horror of separation from God in his death on the cross. If we entrust ourselves to Jesus we can therefore escape judgment and spend eternity in a new and perfect world not hell. 

The amazing thing is not that God sends people to hell, as we all deserve, but that he has made it possible for us to go to heaven, even though we don't deserve to. We cannot blame him if we refuse reject this gift. In the end, everyone get's what they want. Those who show in this life that they want life with Jesus Christ, get it everlastingly. And those who don't, don't.
