There is a natural tension between nurture and evangelism in most groups. Nurture is natural and easy; evangelism is often not as easy. Here is a list of things you can try in your group to keep evangelism as a focus.
Prayer. Pray that the members of your group will begin to have a real heart for the lost and that they will be open to reaching out to others.
More Prayer. During the prayer time in your group, try this kind of idea. Give each person two index cards. Ask participants to write the name of an unchurched person they come in contact with on a regular basis on both cards. Have them put one of the cards into a bowl in the middle of your circle, and then pray as a group for the individuals whose names are on the cards. Ask the group members to keep the other card in a place where it will remind them to pray for the person every day. At following meetings, you can continue to pray for those individuals and begin asking group members to invite their friends to the group.
Vision Casting. Share your vision for evangelism. Don't push your agenda on the group.
Bible Study. Study passages such as Matthew 28:18-20; John 3:16; selections from the book of Acts, particularly chapter 2; Colossians 4:2-6; and others. Or, apply your current study to the meaning of being a witness.
Open Group. Discuss often the fact that your group is open to newcomers. Model this by inviting others.
Empty Chair. Place an empty chair that represents the person who can be invited to your group in the circle at each meeting. Pray for the person who will fill the empty chair.
Topics. As the group begins to get a vision for evangelism, choose Bible books or topics that are relevant to anyone-Christians and non-Christians.
Sharing. Share victories of witnessing ...
