16 So from now on we regard no one from a worldly point of view. Though we once regarded Christ in this way, we do so no longer. 17 Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come! 18 All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation: 19 that God was reconciling the world to himself in Christ, not counting men's sins against them. And he has committed to us the message of reconciliation. 20 We are therefore Christ's ambassadors, as though God were making his appeal through us. We implore you on Christ's behalf: Be reconciled to God. 21 God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.
39 “We are witnesses of everything he did in the country of the Jews and in Jerusalem. They killed him by hanging him on a tree, 40 but God raised him from the dead on the third day and caused him to be seen. 41 He was not seen by all the people, but by witnesses whom God had already chosen--by us who ate and drank with him after he rose from the dead. 42 He commanded us to preach to the people and to testify that he is the one whom God appointed as judge of the living and the dead. 43 All the prophets testify about him that everyone who believes in him receives forgiveness of sins through his name.”
18 Then they called them in again and commanded them not to speak or teach at all in the name of Jesus. 19 But Peter and John replied, “Judge for yourselves whether it is right in God's sight to obey you rather than God. 20 For we cannot help speaking about what we have seen and heard.”
14 How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? 15 And how can they preach unless they are sent? As it is written, “How beautiful are the feet of those who bring good news!”
18 Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. 19 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, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”
8 “But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.”
“Carrying God's gracious offer involves human beings whom God has brought to Himself and then uses as His heralds. They share God's message of salvation because He will save everyone who calls on His name.” Bible Knowledge Commentary
“Sometime after 1950 we forgot what Jesus said to Peter and what was passed on to us. ‘Take care of my sheep’ (John 21:16). ‘There are ferocious wolves’ (Matthew 7:15). ‘You are to be a witness to the ends of the Earth’ (Acts 1:8). This is a commission that still holds true today. This is a very personal command to each believer, personally, privately. The all important question is whether you are getting out the work of God, or have you retired?” Wales Goebel
“Taking a stand for Christ is increasingly unpopular in our pagan and pluralistic society. If you believe that God created the world, that He is a God of both love and holiness, that Jesus died and rose again for our sins and is the only way to heaven, and that we have a responsibility to take that message to a needy world – those beliefs will vilify you in many segments of our society. Our world is determined to intimidate, marginalize, and silence Christians. But our goal isn’t popularity; it’s to know Him and make Him known. We shouldn’t be needlessly offensive, but we shouldn’t be afraid of the ‘offense of the cross’. These are exciting days in which to bear a witness for our Savior!” Robert J. Morgan
