Jesus tells the parable of the talents, that those work and made more talents were given more responsibility and the one who didn't was cast out, is this true for our salvation, do we have to work for it, well no Jesus already did the hard work for us for anyone who believes, but if u have a job u work for a wage and if u good at your job u may get a raise or promotion, the same can be said for the kingdom of heaven, those who do a good job in this life will get more in the next but those who do not even what they have will be taken away, work is an obligation and we should expect no more then our wages and if we do not do our job then we will be out in the gutter.
