Once you come to know Jesus you are no longer lost, you have been saved. The word saved is defined as: to rescue from danger or destruction, to save one from disease, to make well, heal, restore to health, to deliver from the Messianic judgement. If you know Jesus you are no longer lost, you have been saved. You are not going to be you already are. To walk in the reality of all Christ has done for us you must believe in your heart it is already so, for faith does not see what Christ has done for us as a promise to come, but a present day reality. It is no different then salvation for the sinner. God has already done what is needed for one to be born again. They must simply receive by faith what He has already done. And so it is with all we have in Christ, we need to see what He has done as a completed work. When you do then you will walk in what is already yours.
