Ashamed of the gospel?

"I am under obligation both to Greeks and to barbarians, both to the wise and to the foolish. So I am eager to preach the gospel to you also who are in Rome. 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." Romans 1.14-16

Are you eager to preach the gospel, or are you ashamed of it? If you understand the gospel and understand that the gospel is necessary to save sinners (for you yourself have only been saved by hearing it with faith), then why do you not preach it? It is either shame of the gospel and God, or lack of love for the world. Either way, if you find yourself in this condition, pray that God will change your heart and give you a passion for the lost. You are (whether you feel it or not) under obligation, a divine command from Christ, to preach the gospel to all men from all nations (Matt 28.19-20).
