“For the Son of Man has come to save that which was lost.”
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, to heal, restore to health, and to deliver from the Messianic judgement. If you know Jesus as your personal Savior, this complete work of salvation belongs to you. You are not going to be saved, you already are.
To walk in the reality of all Christ has done for us you must believe in your heart that it is already so, for faith does not see what Christ has done as a promise to come, but a present day reality, because faith is present tense (now faith is). It is no different than 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, believing in our hearts we have what He has said. We must agree with God’s Word, declaring what His Word says, and we must act upon His Word, walking by faith and not by sight. When you do then you will walk in what is already yours for you have been saved!
