Do you ever fear talking about your faith? I do. What if they don't care what I have to say? What if they don't listen? What if my words don't come out right? What if it turns them away? But what if God is urging me to talk to them and I refuse out of fear...what then?
As God is preparing Ezekiel to become a prophet in Israel He tells him, "Your job is to speak. Whether they listen is not your concern." (Ezekiel 2:7 msg) Then God promises to strengthen Ezekiel in verse 3:8.
What is interesting to me is that even though God is going to directly give Ezekiel the words to say to his people, he still has a choice as to whether to speak them. The same choice that we have everyday. So God lets Ezekiel know that if he chooses NOT to speak the message that he's been given, God would hold him accountable for the ruin of the people. (Ezekiel 3:20-21) I wouldn't want to be responsible for that.
While you or I, as Christians, may not be commissioned as prophets, we have been commissioned to "go out and train everyone you meet, far and near, in this way of life, marking them by baptism in the threefold name: Father, Son, and Holy Spirit. Then instruct them in the practice of all I have commanded you." (Matthew 28:19-20 msg) I think there are different ways to reach different people. But when I feel that stirring inside me, telling me to share something about my faith with a particular person, I hope to always say "Yes, Lord. I will not fear, for the outcome is up to you. Give me the right words to speak."
