What is it about a person who is really living out the gospel? What is it about them that's so different? It can't be things like knowledge or behavior, for those things just reek of pride and moralism. In Galatians 6:1-10, Paul describes for us what a gospel life looks like. And what Paul does for us is to show us that if the gospel is indeed alive and growing in us, it will be most evident in how we relate to people.
In verses 1-5 of Galatians 6, we are shown what gospel community looks like. Those who are mature in the gospel help guide those who are not and restore those ensnared in sin in a loving and gentle way. We are to help each other in practical ways when life brings us a season that is harder than usual. And, we are to live humbly as we fulfill those responsibilities that are ours alone, and encourage and empower others to do the same.
In verses 6-10, Paul continues his instructions on living out the gospel (still under the umbrella of community). He particularly points out the relationship between teachers & students to be a reciprocal relationship of generosity both relationally and financially (the term "good things" is most certainly a euphemism for giving). Paul then "lays down the gauntlet" and says that if you really want to reap the blessings that God has to offer, you must sow the things that God has ordained (think fruit of the Spirit from Galatians 5:22-23). To not "sow" intentionally what God has ordained yet still expect his blessings is lying to yourself and mocking God. We can't live however we want in our relationships, with our money, or in any other way and still enjoy heaven. It's God's way or no way - it's either Spirit or flesh. Paul then encourages us that we need to be patient. Reaping the things of God doesn't happen overnight...but as we remain faithful and strong in Jesus, we are promised that "in due season we will reap."
Paul ends this great passage with one last encouragement, kind of like a coach in the locker room before the players hit the field. We are to "do good" (in all ways: relationally, financially, serving, etc.) to everyone, and in particular to those who are Christians (especially those in your own church or community group). Why emphasize the "household of faith"? Because of what Jesus Himself said: "They will know you are my disciples by your love for one another" (John 13:35).
This "gospel life" is be lived at every opportunity! Not just when we have time or can squeeze it in. The time to love someone in need is when there is someone in need. It's that simple. We just need to intentionally order our lives so we have the room to love people. Just like Jesus.
