The Scriptures instruct us about the spiritual condition of the early church in Jerusalem, during the time when great grace was upon them.
“And they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart, Praising God, and having favour with all the people. And the Lord added to the church daily such as should be saved” (Acts 2:46-47)
They gathered with one accord. They broke bread from house to house. They ate together with gladness and simplicity of heart. They did not over-engineer it. They just ate together, loving each other. As they lived in good fellowship this way, they had good favor from those who were outside the church. This good favor is not something you can get by “managing your brand”—it has to be the gift of God. And as a consequence of this, the Lord added to their number those who were being saved.
True evangelism is the result of a contagious holiness. Untrue evangelism is simply marketing or recruiting. Because there is some overlap between the two (in both, the word goes out by physical means), the way we keep our evangelism from deteriorating into a scramble for market share is by loving Jesus, and loving our neighbor. We are called to do this, as we partake of the bread and wine, in gladness and simplicity of heart.
And this is only possible as we grasp the gospel. That means, of course, that we see how the gospel has actually grasped us.
So come, and welcome, to Jesus Christ.
