From ages past till now, God don't call lazy people into his vineyard
Moses was busy with his work when God called him
Amos was busy when God called him
God call the best for his purpose
He makes use of the best for his purpose
Gideon's was called valiant man when he was hiding from enemies
God is still in business of calling people till this hour
Don't ignore when he calls you
It is a thing of joy when you are working with the king of kings and the Lord of Lords
It is a good thing to be called with the name of the Lord
