I’ve been taught that whenever I see a “therefore” in Scripture, I ought to ask why it’s there for! When you come across a Bible verse, it’s always good to look at the verses that come before and after, the context, if you will.
In this case, I encourage you to read Galatians 6:7-9, and you will learn that you have a choice in life: You can choose to focus on satisfying yourself (your flesh) OR You can focus on pleasing God (the Spirit). If you focus on satisfying yourself, you will be disappointed, but if you focus on the Spirit and please God, you will be blessed.
What does this look like practically? If you have an opportunity to serve someone or be self serving, choose to serve the other person because of your love for Jesus.
