As His disciples, the people of God are commanded to go, to teach and to baptize and finally to make disciples of those who He adds to the kingdom. We are commanded to preach the gospel of the kingdom to every creature. Every one of us that has been added to the kingdom because of His grace and mercy and love is required to fulfill His command. As they went and did so on the Day of Pentecost, the Lord honored their obedience, faithfulness and effort and He added to the kingdom such as should be saved.
