We often hear repeated the challenge for Christians to be an active participant in taking the gospel throughout the world.  That message came from the lips of Christ as He spoke to His disciples … “Go into all the world and preach the gospel to every creature” (Mark 16:15 NKJV).  And again He said … “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,  teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age" (Matt 28:19-20 NKJV).  Then just prior to his ascension, Jesus informed His followers … “But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth” (Acts 1:8 KJV).  While some rationalize that Jesus was just speaking to His disciples, other passages of Scripture reveal that the opportunity to represent Christ before others is not only a privilege but is mandated for all believers. God always has His witnesses.  In the Old Testament, the message of the coming Savior was entrusted to the nation Israel and her strategic location enabled the known world of that day to hear of the one true God.  Speaking of the nation Israel through the prophet Isaiah, God proclaimed … "You are My witnesses," declares the LORD, "and My servant whom I have chosen, in order that you may know and believe Me, and understand that I am He. Before Me there was no God formed, and there will be none after Me. "I, even I, am the LORD; and there is no savior besides Me. "It is I who have declared and saved and proclaimed, and there was no strange god among you; so you are My witnesses," declares the LORD, "and I am God” (Is 43:10-12 NASB).  The Apostle Paul called the believers in Corinth ambassadors for Christ.  Prior to placing their faith in Christ, they were alienated from God, not having availed themselves of the good news that God had made the entire human race savable, reconciled to God, through the one time sacrifice of Christ on the Cross for sin.  However, upon faith the Christ, these same Corinthians now had a new standing with God.  They were a new creation in Christ and given the privilege and obligation of carrying the message of reconciliation to those without the Savior … “Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come!  All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation: 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” (2 Cor 5:17-19 NIV). The dissemination of the Gospel then is the responsibility of each of us who claim to be a child of God.  Some are called into specific areas of service, but most believers are to stay put, right where they livethat is their mission field – where they work, their family, friends, neighbors, school, and members of the community.  How the good news is given is almost limitless – God opens the door and provides the means.  What’s paramount is our availability and sensitivity to be used by God however and whenever the opportunity arises. God does the work; we are merely instruments, vessels in His service.  The words spoken to Isaiah still resound on willing hearts … “Then I heard the voice of the Lord, saying, "Whom shall I send, and who will go for Us?" Then I said, "Here am I. Send me" (Is 6:8 NASB)!
