Paul lived his life with an urgency for the Kingdom of God. From his calling in Acts 9 he lived a life of urgency in what God called him to do. He did have a time of preparation which are often called the "lost" years in the desert after his conversion. But even there, it is believed that Paul shared the Gospel. His life was committed to proclaiming the Gospel to both Jews and Gentiles. In the book of Acts we see Paul often on the move never staying longer than two years in a place. His mission and focus was clear: share Jesus the Messiah to all. This urgency doesn't mean, he didn't stop to enjoy the time with other believers. He certainly did! He also experienced a lot of trials, tribulations and suffering. But why would Paul live this life of urgency? First, as said before, he knew his calling. (See 1 Corinthians 9:15-16) This calling was directed by the Lord. He was often in prayer, in Scripture and in fellowship with others which the Lord used to direct Him. He also depended on the Holy Spirit for every move. Second, he knew the time was short. He knew that he would not be around for ever. Life was short and he wasted no time. (See Ephesians 5:15-16) Third, He knew what it meant to be lost without Christ. He had grown with religion but didn't know the power of the living Christ. Paul was moved by the love of Christ towards those who had yet to believe in Him. (See 2 Corinthians 5:14-15) It moved him with urgency. Finally, Paul knew the return of Christ was imminent (see 1 Thessalonians 5:1-11). Christ spoke of this urgency and preparedness we ought to have before His coming (see Matthew 24:44-51; 25:1-13). Paul understood and lived with this expectation.
All these reasons are good enough for me and I hope are enough for you to live a life of urgency and not child's play. All of us who have been saved by Christ are called to serve Christ regardless of profesion. Our calling is to make disciples by sharing the Gospel of Christ. (See Matthew 28:19-20) This is urgent. It isn't a trivial pursuit or an added task to our lives. It is our priority. It should be marked with many !!!!!
