Have you ever wondered how Christianity could have spread from the small province of Judea in the Mediterranean basin to reach pretty much every corner of the globe by the 21st century? Have you ever marveled when hearing how Christianity survived, even thrived, in harsh dictatorships and totalitarian regimes? Or have you considered how, generation after generation, parents have successfully passed down their faith to their children in countries where believers are a minority within the broader culture? Have you ever wondered how people who are considered hardened criminals can find faith even while locked away in prison?

Amazingly enough, faith in Christ is spread most effectively on a personal basis by individuals sharing the gospel. From the first followers of Jesus along the streets of Judea, to you and me today, God’s plan has always been the same: Simply spread the good news. Jesus said, “As the Father has sent me, even so I am sending you” (John 20:21).

The late Reverend Billy Graham, who led millions of people to faith in Christ through mass meetings in evangelistic tours, understood the importance of the personal touch. After each event,  small teams of believers were available to connect individually with those who had accepted Jesus, so they could offer them guidance and support in their newfound faith.

This month’s issue of Activated features testimonies, tips, strategies, and encouragement to aid us in what is often called the “Great Commission,” which is Jesus’ challenge to His followers to “go into all the world and proclaim the gospel to the whole creation” (Mark 16:15).
