Acts 8:8 And there was great joy in that city.
Have you stopped to think about what happens when you tell others about Christ? Have you stopped to think what a difference you can make?
If you are looking for encouragement to go out and tell people about Christ, then start reading the book of Acts!
The more the Apostles were able to tell others about the Gospel, the more the people would become encouraged and filled with joy!
If you want to make someone truly happy, then allow them to see the same truth about Christ you have grown to know and love!
