ASHAMED?

Rom 1:16
16 For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek.
NASU
** Ashamed? What would that entail? If you are a Christian and the Gospel is the power of God for salvation and you are ashamed of the Gospel then that would be like being ashamed of the motor that propels the vehicle that you are riding in. Are you ashamed of the power that propels you? We need the power that propels us and if we are making that power available to other people to be their power, then being ashamed of it would limit us telling others about it. I know this seems confusing but the basic concept is this; That which you are proud of you will not be able to keep your mouth shut about. If you are proud of the Gospel then you will be telling others about the gospel…. If you are ashamed of the gospel, you will not be sharing it with others around you. So….. why are you not sharing the gospel…. Ashamed?
