Mark 5:19 “Go home to thy friends, and tell them how great things the Lord has done for thee.”
These were the words of the Lord to the man who had been possessed by a legion of demons. The Lord had cast them out, and now the man wanted to go with the Lord as He was leaving. But the Lord told him to go back to his friends and give them the Gospel message: The great things He has done. Most of what goes under the name of preaching is the great things He will do if…. That does my soul no good because I know where that will go. In reality, that is a message of salvation by works. Christ will do this if you do something that will obligate Him to respond. The message of the Gospel is what He has done! He did not say, “It will be finished if….” but “It is finished!” No if’s, nothing I need to do to complete it. Every aspect of salvation, from pre-destination to glorification has been done (Romans 8:31-35). A sinner can rest in what the Lord has done!
