A. W. Tozer reminds us that the purpose of evangelism is worship, which means that worship has ultimate priority for man.
"It's more important that the Church of Christ should honor the God of glory than they should even preach the gospel to the heathen. But it is so in the will of God that preaching the gospel to the heathen and getting them saved will, as Paul said, bring more people to praise him, so that we glorify God by winning more people. But if you had to take your choice, honoring God would be first."
from the sermon "Worship the Lord in Glory in Meekness," in the Worship Series.
