The Question of 'What If'

The first section presents three fundamental truths about human decision-making. No one in life can make decisions or act perfectly; everyone makes mistakes and subsequently regrets them, asking 'what if' they had chosen differently. The 'what if' question concerns not only minor matters like fashion or marriage choices, but also major decisions that profoundly affect life, haunting a person for years like unhealed wounds. The sermon uses historical examples (Emperor Quang Trung) and Scripture (Adam, Eve, Noah) to illustrate that even great figures experienced wrong decisions they had to regret.

The second section develops content by introducing detailed backgrounds of Paul and Barnabas—two important figures in church history. Paul is described as a great Christian, intelligent, courageous, wholehearted in his love for God, author of at least 13 books in the New Testament, and having traveled over 13,000 miles in missionary work. Barnabas—whose name means "son of encouragement"—was the person who introduced Paul to the apostles in Jerusalem when no one trusted Paul. Barnabas later found Paul in Tarsus and brought him to the church in Antioch to minister and teach together. The two had served God together for over 12 years, experiencing countless hardships and trials.

The third section details the conflict between the two over whether to take John Mark—Barnabas's cousin—on the second missionary journey. Mark had abandoned them during the first journey in Pamphylia. Barnabas, the encourager, wanted to give Mark a second chance due to family affection and because God had forgiven them. Paul, the careful reasoner, feared Mark would quit again, damaging believers' faith and jeopardizing the crucial missionary work. The dialogue became increasingly heated until they separated, Barnabas going with Mark to Cyprus, while Paul went north with Silas.

The fourth section discusses lessons from this event. The sermon notes that Scripture does not say who was right or wrong, merely recording the fact. That Paul still mentioned Barnabas 6-10 years later in his letters indicates lingering sadness and regret. The sermon emphasizes that even mature believers devoted their entire lives to God cannot always fully resolve disagreements. We must accept our limitations and seek reconciliation as best we can while recognizing that this is not always possible. Yet God still used both teams (Paul-Silas and Barnabas-Mark) to spread the Gospel, and Mark eventually became a faithful servant whose writing of the Gospel of Mark was canonized.

The final section concludes with three key lessons: first, we need balance between the heart (emotion) and mind (reason); second, an effective life principle is "In essentials unity, in non-essentials liberty, in all things charity"; third, we must not let the past imprison the present, but forget what lies behind and press forward as Paul teaches. God uses all circumstances—whether good or bad—to work together for good for those who love God according to His purpose.
