Judge the world in righteousness

With reference to Acts 17:7,31—After He rose from the dead He commanded the apostles, saying go preach the gospel to every creature: he that believes and is immersed shall be saved: and he that believes not shall be condemned," and "lo, I am with you unto the end of the world." In view of these texts can anyone be so mystified as not to see that salvation is predicated on believing the gospel of the kingdom, and being baptized into Jesus Christ? They were to preach "this gospel of the kingdom" in the name of Jesus; how did they execute the work? "They went forth and preached everywhere, the Lord working with them, and confirming THE WORD with signs following" (Mark 16:20). They began at Jerusalem, passed throughout Judea, then went to Samaria, and, lastly, to the end of the land (ESCHATOU TES GES). They began on the day of Pentecost and preached only to the Jews for several years, at the end of which Peter and Paul began to proclaim the kingdom to Gentiles also. The labors of the apostles were indefatigable. They filled the Roman empire with their doctrine, and made such an impression upon it that tumults were excited, and they were charged with treason against the state, because they proclaimed another king than Caesar (Acts 17:7, 31) who should rule the world in righteousness as the sovereign Lord of all the earth. "They spake the word of God with boldness." "The multitude of them that believed were of one heart and of one soul," and great kindness was among them all. In about thirty years the gospel of the kingdom was proclaimed in all the world, to every creature under the heaven (Col.1:6, 23). They finished their work, and fell asleep, the Lord having abundantly fulfilled His promise of co-operating with them to the end of the world.
