There are three doors that can be opened before a person receives the good news of Jesus Christ:
1. Lord, open a door of opportunity. "That's a natural opportunity for me to bring up my relationship with Jesus," explains Hutchcraft. "So, Lord, open the door. He'll do that."
2. Open their heart. "If You're putting them on my heart to talk to them, would You get their heart ready for when I do? Open their heart."
3. Open my mouth. "Give me the courage. Give me the words when it's the time. Give me the tone."
