Acts 14  Paul and Barnabas continue their journey, going to Iconium, where Jewish unbelievers stirred up the Gentile unbelievers until there is an attempt to stone them.  Then they go to Lystra and Paul heals a man who had not walked since birth and the people want to offer sacrifices, thinking that Paul and Barnabas are actually Zeus and Hermes... until the Jews come down from Iconic and they actually do stone Paul.  Yet, Paul gets up and they go to Derbe where the preach again.

After this Paul and Barnabas go back through the cities they visited, "strengthening the souls of the disciples, encouraging them to continue in the faith, and saying 'Through many tribulations we must enter the kingdom of God'" ( v22)

Then Paul and Barnabas return home and report all that God had done, " and how He had opened a door of faith to the Gentiles." ( v27)

Paul faithfully preached the Gospel and the Lord "was bearing witness to the word of His grace, granting signs and wonders."    In verses 15 -17 Paul explains his motivation to keep preaching, " in order that you should turn from these vain things to a living God who made the Heaven and the earth, and the sea and all that is in them. And in the generations gone by He permitted all the nations to go their own ways; and yet He did not leave Himself without witness, in that He did good and gave you rains from heaven and fruitful seasons satisfying your hearts with food and gladness." 

Do we share Paul and Barnabas's determination and motivation to share the gospel?  Let us keep on preaching the gospel of Jesus Christ with the understanding that those who do not know Him are serving "vain things" -empty, useless, and temporary things, like money, power, material goods...
We serve a living God Who made the heavens and the earth, the sea and all that is in them!  We serve God, Who gives us grace and mercy - doing good for us and we need to honor and acknowledge Him continually.

Father in Heaven, hallowed be Your Name!  May Your kingdom come!  May Your will be done on earth as it is in Heaven.  Give us today our daily bread.  Forgive us this day our sins as we forgive those who sin against us.  Lead us not into temptation, but deliver us from the evil one.  For the Kingdom, the Power, and the Glory are Yours alone!
Amen
