Hello Mr. Farah:
I made a Gospel tract and “defined” the Gospel as:
The Gospel (Good News) is Christ’s death on the cross as an atoning sacrifice (paid the penalty) for the sins of all those who would ever repent of their sins and trust in Jesus Christ as their Savior and Lord.
Hope this helps. I know there is a lot more to it.
We all enjoy your articles. And we thank God for WND. May God continue to richly bless you.
