I hear calvinists on the forum frequently exclude the gospel as the means of Gods grace in salvation.
Acts 14:3- So Paul and Barnabas spent considerable time there, speaking boldly for the Lord, who confirmed the message of his grace by enabling them to perform signs and wonders.
Acts 20:24- But I do not account my life of any value nor as precious to myself, if only I may finish my course and the ministry that I received from the Lord Jesus, to testify to the gospel of the grace of God.
Romans 1:16- For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
Why are you ashamed of the gospel of grace which is the power of salvation- to and for ALL THOSE WHO BELIEVE ?
hope this helps !!!
