The best thing that ever happened to me occured on July 24, 1972. That evening, I met Jesus Christ.
He changed my life completely, and replaced my teenage anxiety and confusion with His love and peace. Immediately, I wanted to tell everyone that I knew about this wonderful Savior. I had the privilege of sharing the Gospel with my family, and saw my Mom, my brother, my sister, and my Father all come to faith in Christ within a six-month period. I shared the good news with class mates as well, and saw many of them come to faith in Christ.
I have shared Christ in various places around the world since that time, and have been blessed to see many embrace Christ as their Savior. The message of the Gospel is the best one that I could ever give to anyone, and it is a continual joy to see Christ save many as I share Him.
That joy of seeing someone come to Christ is so great that it excites me each and every time. Yes, there have been those who have rejected the message, and those who have persecuted me as a result of that message, but God is faithful, and keeps His joy alive inside of me.
Why do I share the Gospel? Because His love and joy within me is so great I want everyone to experience it as I have.
Whosoever is thirsty will come. Those that aren't won't. This is 100% the Calvinist position. If it were not, I'd be ashamed of the name.
