Career plans determine time priorities rather than guidance from our heavenly Father who first called us into medicine. This is an almost uniform finding in those whose faith has survived. Through this they have gained Christian support outside of medicine. It is not easy to live such a life because it means denying yourself and some of the things that you enjoy. I believe it involves an initial, and then daily, point of total surrender to him.
Repentance has to be more than 'saying sorry'.
This is true revival as his life is poured into ours. Once we have tasted of how good his life is, we will be much more reluctant to ever let it go or, in other words, allow our faith to slip. Tim Lyttle is available to speak at CUs on this and other topics. Further reading is available from CMF on request. There is not space here to discuss if believers can lose their salvation.
