In other words, salvation is not dependent upon what I do, but upon what Christ has done. At a very young age, that little girl was voicing exactly what the Holy Spirit is teaching through Paul concerning the believer's salvation in Christ. Humans still must go through physical death. Such a comment seems like a good rational objection. However, this objection overlooks the fact that physical death does not determine where one is going to spend eternity.
Sin determines where one is going to spend eternity.
The sting of sin and death is gone through Christ's victorious death and resurrection. The sting of death is sin , and the power of sin is the law. In terms of the process of redemptive history, the believer's present actual state of existence is one of union with Christ in his death and resurrection. When Scripture commands us to set our hearts and minds upon things that are above, it is not expressing an ideal which cannot be reached. Moreover, it is not a hypothetical goal which cannot be attained.
