'Gospel of God' in the Bible

separated unto the gospel of God, (which He had promised before by his prophets in the holy scriptures) concerning his Son,

that I should be the minister of Jesus Christ to the Gentiles, administring the gospel of God, that the offering of the Gentiles might be acceptable, being sanctified by the holy Spirit.

Have I committed an offence in humbling myself that ye might be exalted? and in that I have preached the gospel of God to you gratis?

But though we had suffered before and been injuriously treated, as ye know, at Philippi, we spake boldly in the name of our God to declare unto you the gospel of God with much conflict.

so we, being affectionately desirous of you, were willing to impart to you, not only the gospel of God, but even our own souls, because ye were dear unto us.

For ye remember, brethren, our labor and toil; for working night and day, that we might not be burthensome to any of you, we preached among you the gospel of God.

For the time is coming when judgement is to begin at the house of God: and if at us first, what will be the end of those that obey not the gospel of God?
