The earth is being filled with the word of God in fulfilment of prophecy. Isaiah 11:9 says the earth shall be full of the knowledge of the Lord as the waters cover the sea. The Early Church did a lot to spread the gospel in their time, and they accomplished so much; Acts 19:20 says the word of the Lord grew mightily and prevailed.
It has been said that there are two kinds of men: the actors and the spectators. While some are doing so much to promote the gospel in obedience to the Great Commission, others are simply doing nothing. Nobody should be a spectator in this matter. All hands must be on deck. Apostle Paul was so involved that whether he was in chains or free, he was always engaged in spreading the gospel.
With social media, anyone can preach the gospel free of charge! Apart from social media, actively engage in other areas: preach to people around you, join your church for evangelism, pray for the lost, for evangelists and missionaries, pray for open doors and open hearts, pray against the activities of Satan, support the gospel financially and materially: just make sure you do something all the time.
Paul wrote to the Philippians, "Whether I come to see you, or else be absent, I may hear odd your affairs, that years stand fast in one spirit, with one mind striving together for the faith of the gospel." Philippians 1:27. Refuse to be the odd man out. Refuse to be quiet. Make a difference in the lives of others! Be a soul winner. Life without Jesus is miserable: why not partner with God to save souls.
