Preach the gospel!

Then I saw another angel flying in midair, and he had the eternal gospel to proclaim to those who live on the earth-- to every nation, tribe, language and people. He said in a loud voice, "Fear God and give him glory, because the hour of his judgment has come. Worship him who made the heavens, the earth, the sea and the springs of water."

Revelation 14:6,7 NIV


NOW I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain. For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, and that He was buried, and that He was raised on the third day according to the Scriptures.

1 Corinthians 15:1-4 NASB


And He said to them, Go into all the world and preach the gospel to all creation. He who has believed and has been baptized shall be saved; but he who has disbelieved shall be condemned.

Mark 16:15,16 NASB
