'Gospel of God' in the Bible

Now after John was put in prison, Jesus came to Galilee, preaching the gospel of God,

Paul, a servant of Jesus Christ, called to be an apostle, set apart for the gospel of God

to be a minister of Christ Jesus to the Gentiles in the priestly service of the gospel of God, so that the offering of the Gentiles might be acceptable, sanctified by the Holy Spirit.

Or did I commit a sin in humbling myself that you might be exalted, because I preached the gospel of God to you without charge?

but after we had already suffered and been shamefully treated in Philippi, as you know, we had the boldness in our God to speak to you the gospel of God in the face of great opposition.

Having so fond an affection for you, we were ready to share with you not only the gospel of God but also our own lives, because you had become very dear to us.

For you remember our labor and toil, brethren; we worked night and day, that we might not be a burden to any of you, while we preached to you the gospel of God.

For it is time for judgment to begin with the household of God; and if it begins with us, what will be the outcome for those who do not obey the gospel of God?
