When God called Ezekiel, He did it in visions, elaborate and astounding visions. But there are some very important principles here.
First, be sure this is God's calling, not just man's ideas. Only God can make a call fruitful. And the Holy Spirit gives the strength to follow through.
Second, fill yourself with the Word of God. It is the source of your power and knowledge. God Himself sets it forth as a requirement before Ezekiel can go forth and speak to the people.
Third, your response to the call cannot be based on people's reactions to your message. You are responsible to God, not man, to be faithful to what you are told to say.
Ezekiel is not the only one called of God. Each of us has a call of God upon his life. God has a specific purpose for each of us. Our faithfulness to that call is the standard by which we should measure our success in life. It has nothing to do with what people think of us. It has everything to do with what God has called us to accomplish.
Help us to remain faithful to Your call upon our lives. Give us a clear vision of what You would have us do and imbue us with the power and perseverance to do it.
In Jesus' most precious name.
