Acts 13:38-44
New King James Version (NKJV)
Unconditional Gospel
38 Therefore let it be known to you, brethren, that through this Man is preached to you the forgiveness of sins; 39 and by Him everyone who believes is justified from all things from which you could not be justified by the law of Moses.40 Beware therefore, lest what has been spoken in the prophets come upon you:
41 ‘Behold, you despisers,
Marvel and perish!
For I work a work in your days,
A work which you will by no means believe,
Though one were to declare it to you.’”
Blessing and Conflict at Antioch
42 So when the Jews went out of the synagogue, the Gentiles begged that these words might be preached to them the next Sabbath. 43 Now when the congregation had broken up, many of the Jews and devout proselytes followed Paul and Barnabas, who, speaking to them, persuaded them to continue in the grace of God.
44 On the next Sabbath almost the whole city came together to hear the word of God.
The Grace of Christ is the THE Gospel
Galatians 1:6-9
New King James Version (NKJV)
6 I marvel that you are turning away so soon from Him who called you in the grace of Christ, to a different gospel, 7 which is not another; but there are some who trouble you and want to pervert the gospel of Christ. 8 But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed. 9 As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed.
The whole counsel of God
Acts 20:24-27
New King James Version (NKJV)
24 But none of these things move me; nor do I count my life dear to myself, so that I may finish my race with joy, and the ministry which I received from the Lord Jesus, to testify to the gospel of the grace of God.
25 “And indeed, now I know that you all, among whom I have gone preaching the kingdom of God, will see my face no more. 26 Therefore I testify to you this day that I am innocent of the blood of all men. 27 For I have not shunned to declare to you the whole counsel of God.
