Saved by Christ's Life

"To know that we are secure in Christ is a great assurance to live in this world today. "... but God shows his love for us in that while we were still sinners, Christ died for us. Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God. For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life." Romans 5:8-10 * What are the dispensations? Are Paul's writings only for the Gentiles? * What do you say to someone who says, "I have to get right with God"?
