What does Luke 4:43 mean?
It would have been good for Jesus to stay in the area near Simon Peter's home (Luke 4:38–41), teaching and healing. However, that is not the purpose for which God called Him. This verse is an example of the difference between "good" and "better," or between "better" and "best." In this earthly life, we are limited in time and resources. We cannot literally do everything for everyone. Part of spiritual maturity is knowing how and when to say "no" to good things, so we can focus on the "best things" to which we are called.In this case, Jesus could not stay because He needed to spread God's message to other areas. Remaining in one town to establish the gospel is noble. That's a worthy calling, but it wasn't Jesus' calling in that moment. His mission was to fulfill the will of God (John 5:36), which meant visiting other places and other people (Luke 19:10).
