So God created man in His own image; in the image of God He created him; male and female He created them. Then God blessed them, and God said to them, “Be fruitful and multiply; fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that moves on the earth.” (Genesis 1:27-28)
Now I don’t believe this was only to be a physical multiplication, it was also to be a spiritual multiplication. As Adam and Eve multiplied physically they would fill the earth with others like themselves; people who knew God and talked with God. They would fill the world with people who had an intimate relationship with God walking in fellowship with Him. They would be reproducing spiritually as well as physically.
The fall of man into sin interfered with this process (Genesis 3). Sin interfered with this multiplication. Sin resulted in physical death which hindered physical multiplication (Genesis 2:17). It also caused spiritual death which is the spiritual separation of sinful man from a righteous God. This you could say hindered spiritual multiplication. Just a little bit.
But because God loves man so much, He made a special plan to save all people, to save you and me, from this terrible spiritual death. God sent Jesus Christ to die for the sins of all mankind. Jesus paid the penalty of death in our place, but not only that, He overcame death for us by rising again from the dead (John 20).
Even though each for us has had this debt paid, we have to individually choose to accept God's plan of salvation by asking forgiveness for sin and accepting Jesus Christ as our Saviour. I know what you’re thinking, “Walter! No kidding? Jesus died to give us eternal life? Why have I never heard this message before?” Consider this. As a believer in Jesus, with all of our sins forgiven you are not just saved from a physical death; you are saved from spiritual death.
In the beginning of the world, God's first command to His newly created people was to multiply. As born-again recreated believers His first command to us is the same. We are to multiply spiritually and fill the earth with others like ourselves; people who love God, who want a relationship with God. Filling the earth with people who know His voice and follow Him.
In Luke 5:10 as Jesus called James and John and the other apostles to follow Him He told them they would become “fishers of men”. His first instruction to His followers was a call to spiritual multiplication. In Acts 1:8 Jesus’ last command to believers was to multiply spiritually. To meet the challenge of reaching out and saving the thousands of people who are needlessly dying in sin without the Gospel. Each and every believer is called to become spiritually reproductive, called to learn the principles of the Gospels of Christ and share them with the unchurched.
This is evangelism, and it is not just for pastors, not just for those who hold a position in the church, not just for those who have a degree. I’m not saying we all need to pick up bible tracks on the way out and go door to door sharing the Gospel, and I’m not saying we need to stand on street corners downtown picking theological arguments with passing atheists either. I am saying that we need to start looking for opportunities to share the Gospel with others, and when we see those opportunities we need to have the courage to step up and do what God has called us to do. We need to have a fire lit under us for evangelism.
