Knowing when someone is ready to hear the gospel message. Knowing when someone is hurting and hiding it. Empathy, sensing what another is feeling, feeling it with them. The gift of tongues is also a part of this category. Christians, you know, have our own 'churchy' language, and that sometimes gets in the way of soul-winning.
Evangelists have a knack for hearing and talking the language of the people.
To speak the language of teenagers, for instance. To hear and understand the spiritual desperation which fuels rap music. Or to hear and understand the spiritual desperation which lies behind the grumbling of grouchy older people. Evangelism, spreading the word for the common good. Teaching, healing, the gift of organization, and the gift of evangelism.
