You are called to be a witness, not a judge.
I -- Inquire with Good Questions.
"Tell me, what are your spiritual beliefs?"
"To you, who is Jesus?"
T -- Take the Common Ground
Look for the things you have in common. The Gospel flies best on the wings of relationship. Find your point of agreement, looking for a connection rather than an argument.
N -- Negotiate the Terms
Be honest and respectful. If they don't want to have a spiritual conversation, respect them, They are people, not projects. nobody wants to be someone's project.
E -- Explain your Testimony (Faith Story)
Nobody can argue with your own personal experience.
You'll never experience this conversation:
"I felt such forgiveness, love and joy!"
"No You didn't!"
S -- Stick to the Main Issues
Don't get caught up in doctrinal debates and arguments over sideline stuff. Keep the main thing the main thing. What's the main thing?
- All summed up in one word -- one person -- Jesus!
Go the direction the Holy Spirit nudges. Follow His lead and He will take you to the people you re to bless and encourage. Go with the flow!
