He demonstrated that God wants people delivered from ignorance, sickness, death, and eternal damnation. At the cross event Jesus testified of the love of God for mankind and the lengths to which he was willing to go to save man from his sins and from himself. At the resurrection Jesus showed that he was more than able to save any who would come to him. The Messiah is more than capable of saving anyone in any situation if they are willing to come to him for deliverance. We are no longer looking forward in time to the day that Messiah will come.
Salvation is here and now.
The church today needs to understand that our work was predefined for us by Jesus while he was still on earth. Jesus came to save, the church is here to save. Today's church can be effective if it will take this matter of salvation seriously. Not its own salvation, but the salvation of the world around it. We have become experts in excuses.
