"Sing to the LORD; praise his name. Each day proclaim the good news that He saves. Publish His glorious deeds among the nations. Tell everyone about the amazing things He does. Great is the LORD! He is most worthy of praise! He is to be feared above all gods."
(Psalm 96: 2-4)
"Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
"And the gospel must first be preached to all nations."
"And he said unto them, Go ye into all the world, and preach the gospel to every creature."
“I tell you, whoever publicly acknowledges me before others, the Son of Man will also acknowledge before the angels of God. But whoever disowns me before others will be disowned before the angels of God."
Again Jesus said, “Peace be with you! As the Father has sent me, I am sending you.”
"But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear..."
(1 Peter 3:15)
