Will Metzger in his book Tell the Truth argues that worship is the most important priory to God and evangelism is the second. If churches kept to this truth more evangelism would be happening. He then quotes John Piper whom says that missions exists because worship does not. He also says that the goal in evangelism is not to get decisions, but to get worshipers. However I am also reading another book on Evangelism and in this one the author argues that aggressive soul-winning is God's number one priority. The author even tells a story of a man led by the Holy Spirit into the woods to a deserted area with no one there but the trees, the rabbits, and the birds. The man preaches a sermon and then leaves only to find out years later someone got saved. This author tells lots of encouraging stories, cites lots of verses, and makes a strong case for active evangelism on a weekly basis. So according to the Bible what author is correct? You must test your authors with the Word of God.
