"37 and when they found him, they exclaimed: “Everyone is looking for you!” 38 Jesus replied, “Let us go somewhere else—to the nearby villages—so I can preach there also. That is why I have come.”" -Mark 1:37-38
Why would Jesus leave a place where people were looking and asking for His help? Sometimes listening to God requires you to leave great ministry opportunities. God had an assignment for Jesus elsewhere even though there was still work to be done where he was at. Jesus had to follow the God's plan and calling God first. He knew He was fulfilling His calling when He turned down one invite and said, "Let us go somewhere else—to the nearby villages—so I can preach there also. That is why I have come.”
Though it may seem backwards, leaving and saying goodbye can sometimes be the healthiest decision, even if the goodbye brings you sadness and confusion. If you still see more to be done in the place you're leaving behind, it means you love and believe in the people or place.
Sometimes people leave a place and others can't wait for them to leave. Often the person moving can't wait to leave either, but they aren't necessarily leaving well. So what does it mean to leave well? Leaving well means both parties can celebrate that God is not finished working in either place. It's also knowing the investment you made was worth your time and effort, and the people you are leaving are healthier rather than bitter.
While God usually gives us a sense of release when it's time to move, know that if it's difficult leaving places you've loved and invested in. This is because you can still see how much God wants to do there. That's really good! You're probably leaving in a healthy place instead of place of being toxic, embittered, or "overstaying your welcome."
If the place you have left celebrates your return, then you know you've left well.
