He said to them, "Go into all the world and preach the gospel to every creature." (Mark 16:15)

You shall receive power when the Holy Spirit has come upon you; and you shall be witness to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth. (Acts 1:8)

You are the salt of the earth; but if the salt loses its flavor, how shall it be seasoned? It is then good for nothing but to be thrown out and trampled underfoot by men. You are the light of the world. A city that is set on a hill cannot be hidden. Nor do they light a lamp and put it under a basket, but on a lampstand, and it gives light to all who are in the house. Let your light so shine before men, that they may see yur good works and glorify your Father in heaven. (Matthew 5:13-16)

I was hungry and you gave Me food; I was thirsty and you gave Me drink; I was a stranger and you took Me in; I was naked and you clothed Me; I was sick and you visited Me; I was in prison and you came to Me. Then the righteous will answer Him, saying, "Lord, when did we see You hungry and feed You, or thirsty and give You drink? When did we see You a stranger and take You in, or naked and clothe You? Or when did we see You sick, or in prison, and come to You?" And the King will answer and say to them, "Assuredly, I say to you, inasmuch as you did it to one of the least of these My brethren, you did it to Me." (Matthew 25:35-40)

And whoever gives one of these little ones only a cup of cold water in the name of a disciple, assuredly, I say to you, he shall by no means lose his reward. (Matthew 10:42)

God is not unjust to forget your work and labor of love which you have shown toward His name, in that you have ministered to the saints, and do minister. (Hebrews 6:10)

Pure and undefiled religion before God and the Father is this: to visit orphans and widows in their trouble, and to keep oneself unspotted from the world. (James 1:27)

If a brother or sister is naked and destitute of daily food, and one of you says to them, "Depart in peace, be warmed and filled," but you do not give them the things which are needed for the body, what does it profit? Thus also faith by itself, if it does not have works, is dead. (James 2:15-17)

So the people asked him, saying, "What shall we do then?" He answered and said to them, "He who has two tunics, let him give to him who has none; and he who has food, let him do likewise." (Luke 3:10, 11)
