2. GETTING UNBELIEVERS INTO WORSHIP
The numbering is not a mistake.This task actually comes second, but nearly everyone thinks it comes first! It is natural to believe that non-Christians must get into worship before “doxological evangelism” can begin. But the reverse is the case. Non-Christians do not get invited into worship unless the worship is already evangelistic. The only way to have non-Christians in attendance is through personal invitation by Christians.
1. MAKING WORSHIP COMPREHENSIBLE TO UNBELIEVERS
Our purpose is not to make unbelievers comfortable. (In 1 Corinthians 14:24–25 or Acts 2:12, 37, theycut to the heart!) We aim to be intelligible to them. We must address their heart secrets (1 Cor. 14:25). That means we must remember what it is like to not believe; we must remember what an unbelieving heart is like.
3. LEADING TO COMMITMENT
Our experience has shown that unbelievers in worship actually “close with Christ” in two basic ways. Some may come to Christ during the service itself (1 Cor. 14:24-25); others must be followed up very specifically.
