An Arabian sultan was surprised by Western missionaries who had come to his kingdom to build schools, roads, and health centers instead of staying in their prosperous home societies. When he asked if they did this for a place in heaven, they answered no - they were obeying Jesus's command to preach salvation to all, since He had already earned heaven for them through His death on the cross. The document discusses how Jesus provided everything needed for salvation and entrance into heaven through His crucifixion, and that Christians should appreciate this by preaching Christ to sinners as the missionaries did.
