Romans 6:17-21

17 But thanks be to God that, though you used to be slaves to sin, you have come to obey from your heart the pattern of teaching that has now claimed your allegiance. 18 You have been set free from sin and have become slaves to righteousness.

19 I am using an example from everyday life because of your human limitations. Just as you used to offer yourselves as slaves to impurity and to ever-increasing wickedness, so now offer yourselves as slaves to righteousness leading to holiness. 20 When you were slaves to sin, you were free from the control of righteousness. 21 What benefit did you reap at that time from the things you are now ashamed of? Those things result in death!

Philippians 2:3

Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves.

IMO

Whether you are a believer or not- there are passages in the Bible that just make sense. If you want to be a better human being, humility and common sense are keys.
