13 As for you, brothers, do not grow weary in doing good.
Once we have been bought with the price of the precious blood of Christ who has freed us from the bondage of sin, who has removed our heart of stone and given us a heart of flesh, who imparts to us the Spirit that we might live a life that is pleasing to God, not by our works, but because of the work already done for us in Christ Jesus. So what does the new life in us do? It goes about doing good. In the immediate context Paul is speaking about doing good in having a job, earning your keep and not being a burden to others. So then, we fulfill Paul’s encouragement to the believers when we are faithful in doing good in our vocations. So if you drive a bus, drive it well. If you are a teacher, teach well. If you are a nurse, do nursing well. But your vocation is not just your job, because we all have many vocations like son or daughter, mother or father, husband or wife, all of these are our vocations as well and we should not grow weary in doing good in any of these vocations as well. When you do them well this is how you are loving and serving your neighbor. So, keep that in mind and don’t grow weary, but love your neighbor, by going about and doing good.
